Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512328, here are decompositions:
- 137 + 31512191 = 31512328
- 167 + 31512161 = 31512328
- 257 + 31512071 = 31512328
- 269 + 31512059 = 31512328
- 311 + 31512017 = 31512328
- 317 + 31512011 = 31512328
- 347 + 31511981 = 31512328
- 359 + 31511969 = 31512328
Showing the first eight; more decompositions exist.
