Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626144, here are decompositions:
- 13 + 31626131 = 31626144
- 71 + 31626073 = 31626144
- 103 + 31626041 = 31626144
- 157 + 31625987 = 31626144
- 163 + 31625981 = 31626144
- 181 + 31625963 = 31626144
- 191 + 31625953 = 31626144
- 227 + 31625917 = 31626144
Showing the first eight; more decompositions exist.
