Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529730, here are decompositions:

  • 13 + 31529717 = 31529730
  • 53 + 31529677 = 31529730
  • 59 + 31529671 = 31529730
  • 61 + 31529669 = 31529730
  • 79 + 31529651 = 31529730
  • 101 + 31529629 = 31529730
  • 107 + 31529623 = 31529730
  • 137 + 31529593 = 31529730

Showing the first eight; more decompositions exist.
