Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497958, here are decompositions:
- 17 + 31497941 = 31497958
- 29 + 31497929 = 31497958
- 131 + 31497827 = 31497958
- 251 + 31497707 = 31497958
- 257 + 31497701 = 31497958
- 389 + 31497569 = 31497958
- 431 + 31497527 = 31497958
- 467 + 31497491 = 31497958
Showing the first eight; more decompositions exist.
