Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563718, here are decompositions:
- 47 + 31563671 = 31563718
- 71 + 31563647 = 31563718
- 149 + 31563569 = 31563718
- 167 + 31563551 = 31563718
- 191 + 31563527 = 31563718
- 227 + 31563491 = 31563718
- 317 + 31563401 = 31563718
- 359 + 31563359 = 31563718
Showing the first eight; more decompositions exist.
