Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497296, here are decompositions:
- 3 + 31497293 = 31497296
- 13 + 31497283 = 31497296
- 67 + 31497229 = 31497296
- 73 + 31497223 = 31497296
- 109 + 31497187 = 31497296
- 139 + 31497157 = 31497296
- 157 + 31497139 = 31497296
- 163 + 31497133 = 31497296
Showing the first eight; more decompositions exist.
