Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605046, here are decompositions:
- 17 + 31605029 = 31605046
- 29 + 31605017 = 31605046
- 59 + 31604987 = 31605046
- 113 + 31604933 = 31605046
- 197 + 31604849 = 31605046
- 257 + 31604789 = 31605046
- 359 + 31604687 = 31605046
- 419 + 31604627 = 31605046
Showing the first eight; more decompositions exist.
