Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511470, here are decompositions:
- 47 + 31511423 = 31511470
- 149 + 31511321 = 31511470
- 239 + 31511231 = 31511470
- 257 + 31511213 = 31511470
- 281 + 31511189 = 31511470
- 359 + 31511111 = 31511470
- 401 + 31511069 = 31511470
- 467 + 31511003 = 31511470
Showing the first eight; more decompositions exist.
