Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555124, here are decompositions:
- 31 + 31555093 = 31555124
- 43 + 31555081 = 31555124
- 61 + 31555063 = 31555124
- 103 + 31555021 = 31555124
- 163 + 31554961 = 31555124
- 241 + 31554883 = 31555124
- 283 + 31554841 = 31555124
- 313 + 31554811 = 31555124
Showing the first eight; more decompositions exist.
