Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562256, here are decompositions:
- 13 + 31562243 = 31562256
- 43 + 31562213 = 31562256
- 137 + 31562119 = 31562256
- 139 + 31562117 = 31562256
- 149 + 31562107 = 31562256
- 157 + 31562099 = 31562256
- 163 + 31562093 = 31562256
- 199 + 31562057 = 31562256
Showing the first eight; more decompositions exist.
