Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563790, here are decompositions:
- 3 + 31563787 = 31563790
- 17 + 31563773 = 31563790
- 53 + 31563737 = 31563790
- 107 + 31563683 = 31563790
- 197 + 31563593 = 31563790
- 239 + 31563551 = 31563790
- 263 + 31563527 = 31563790
- 347 + 31563443 = 31563790
Showing the first eight; more decompositions exist.
