Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497656, here are decompositions:
- 19 + 31497637 = 31497656
- 79 + 31497577 = 31497656
- 97 + 31497559 = 31497656
- 109 + 31497547 = 31497656
- 193 + 31497463 = 31497656
- 373 + 31497283 = 31497656
- 433 + 31497223 = 31497656
- 499 + 31497157 = 31497656
Showing the first eight; more decompositions exist.
