Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512316, here are decompositions:
- 107 + 31512209 = 31512316
- 197 + 31512119 = 31512316
- 233 + 31512083 = 31512316
- 257 + 31512059 = 31512316
- 293 + 31512023 = 31512316
- 347 + 31511969 = 31512316
- 383 + 31511933 = 31512316
- 389 + 31511927 = 31512316
Showing the first eight; more decompositions exist.
