Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77940, here are decompositions:
- 7 + 77933 = 77940
- 11 + 77929 = 77940
- 41 + 77899 = 77940
- 47 + 77893 = 77940
- 73 + 77867 = 77940
- 101 + 77839 = 77940
- 127 + 77813 = 77940
- 139 + 77801 = 77940
Showing the first eight; more decompositions exist.
