Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77916, here are decompositions:
- 17 + 77899 = 77916
- 23 + 77893 = 77916
- 53 + 77863 = 77916
- 67 + 77849 = 77916
- 103 + 77813 = 77916
- 173 + 77743 = 77916
- 193 + 77723 = 77916
- 197 + 77719 = 77916
Showing the first eight; more decompositions exist.
