Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497026, here are decompositions:
- 19 + 31497007 = 31497026
- 37 + 31496989 = 31497026
- 79 + 31496947 = 31497026
- 109 + 31496917 = 31497026
- 163 + 31496863 = 31497026
- 199 + 31496827 = 31497026
- 307 + 31496719 = 31497026
- 349 + 31496677 = 31497026
Showing the first eight; more decompositions exist.
