You're right. There aren't many. Here are some of the more interesting
airport pairs between 7800nm and 8300nm:

SYD-SVO is 7815nm
DFW-BKK is 7853nm
DFW-JNB is 7945nm
ATL-BKK is 7968nm
NRT-CPT is 7970nm
ORD-SYD is 8014nm
ATL-SYD is 8065nm
ORD-SIN is 8144nm
JFK-SIN is 8294nm

Most of these are probably not economically viable at this time, though
a few are.
