Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497350, here are decompositions:
- 13 + 31497337 = 31497350
- 37 + 31497313 = 31497350
- 67 + 31497283 = 31497350
- 127 + 31497223 = 31497350
- 163 + 31497187 = 31497350
- 193 + 31497157 = 31497350
- 211 + 31497139 = 31497350
- 223 + 31497127 = 31497350
Showing the first eight; more decompositions exist.
