Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545088, here are decompositions:
- 5 + 31545083 = 31545088
- 269 + 31544819 = 31545088
- 317 + 31544771 = 31545088
- 431 + 31544657 = 31545088
- 557 + 31544531 = 31545088
- 881 + 31544207 = 31545088
- 1031 + 31544057 = 31545088
- 1049 + 31544039 = 31545088
Showing the first eight; more decompositions exist.
