Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497236, here are decompositions:
- 7 + 31497229 = 31497236
- 13 + 31497223 = 31497236
- 79 + 31497157 = 31497236
- 97 + 31497139 = 31497236
- 103 + 31497133 = 31497236
- 109 + 31497127 = 31497236
- 229 + 31497007 = 31497236
- 373 + 31496863 = 31497236
Showing the first eight; more decompositions exist.
