Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519216, here are decompositions:
- 5 + 31519211 = 31519216
- 17 + 31519199 = 31519216
- 23 + 31519193 = 31519216
- 107 + 31519109 = 31519216
- 149 + 31519067 = 31519216
- 167 + 31519049 = 31519216
- 227 + 31518989 = 31519216
- 263 + 31518953 = 31519216
Showing the first eight; more decompositions exist.
