Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522870, here are decompositions:
- 23 + 31522847 = 31522870
- 47 + 31522823 = 31522870
- 257 + 31522613 = 31522870
- 317 + 31522553 = 31522870
- 347 + 31522523 = 31522870
- 419 + 31522451 = 31522870
- 557 + 31522313 = 31522870
- 593 + 31522277 = 31522870
Showing the first eight; more decompositions exist.
