Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467790, here are decompositions:
- 23 + 31467767 = 31467790
- 71 + 31467719 = 31467790
- 113 + 31467677 = 31467790
- 197 + 31467593 = 31467790
- 239 + 31467551 = 31467790
- 251 + 31467539 = 31467790
- 257 + 31467533 = 31467790
- 281 + 31467509 = 31467790
Showing the first eight; more decompositions exist.
