Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540722, here are decompositions:

  • 13 + 31540709 = 31540722
  • 23 + 31540699 = 31540722
  • 29 + 31540693 = 31540722
  • 43 + 31540679 = 31540722
  • 53 + 31540669 = 31540722
  • 71 + 31540651 = 31540722
  • 79 + 31540643 = 31540722
  • 149 + 31540573 = 31540722

Showing the first eight; more decompositions exist.
