Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529912, here are decompositions:

  • 13 + 31529899 = 31529912
  • 31 + 31529881 = 31529912
  • 163 + 31529749 = 31529912
  • 241 + 31529671 = 31529912
  • 283 + 31529629 = 31529912
  • 373 + 31529539 = 31529912
  • 433 + 31529479 = 31529912
  • 499 + 31529413 = 31529912

Showing the first eight; more decompositions exist.
