Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497254, here are decompositions:
- 3 + 31497251 = 31497254
- 31 + 31497223 = 31497254
- 67 + 31497187 = 31497254
- 97 + 31497157 = 31497254
- 127 + 31497127 = 31497254
- 277 + 31496977 = 31497254
- 307 + 31496947 = 31497254
- 337 + 31496917 = 31497254
Showing the first eight; more decompositions exist.
