Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545196, here are decompositions:
- 5 + 31545191 = 31545196
- 113 + 31545083 = 31545196
- 173 + 31545023 = 31545196
- 227 + 31544969 = 31545196
- 233 + 31544963 = 31545196
- 317 + 31544879 = 31545196
- 479 + 31544717 = 31545196
- 653 + 31544543 = 31545196
Showing the first eight; more decompositions exist.
