Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576104, here are decompositions:
- 13 + 31576091 = 31576104
- 17 + 31576087 = 31576104
- 37 + 31576067 = 31576104
- 67 + 31576037 = 31576104
- 73 + 31576031 = 31576104
- 97 + 31576007 = 31576104
- 101 + 31576003 = 31576104
- 103 + 31576001 = 31576104
Showing the first eight; more decompositions exist.
