Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497170, here are decompositions:
- 13 + 31497157 = 31497170
- 31 + 31497139 = 31497170
- 37 + 31497133 = 31497170
- 43 + 31497127 = 31497170
- 163 + 31497007 = 31497170
- 181 + 31496989 = 31497170
- 193 + 31496977 = 31497170
- 223 + 31496947 = 31497170
Showing the first eight; more decompositions exist.
