Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615126, here are decompositions:
- 17 + 31615109 = 31615126
- 29 + 31615097 = 31615126
- 113 + 31615013 = 31615126
- 173 + 31614953 = 31615126
- 197 + 31614929 = 31615126
- 227 + 31614899 = 31615126
- 293 + 31614833 = 31615126
- 419 + 31614707 = 31615126
Showing the first eight; more decompositions exist.
