Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77964, here are decompositions:
- 13 + 77951 = 77964
- 31 + 77933 = 77964
- 71 + 77893 = 77964
- 97 + 77867 = 77964
- 101 + 77863 = 77964
- 151 + 77813 = 77964
- 163 + 77801 = 77964
- 167 + 77797 = 77964
Showing the first eight; more decompositions exist.
