Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523652, here are decompositions:

  • 5 + 31523647 = 31523652
  • 19 + 31523633 = 31523652
  • 53 + 31523599 = 31523652
  • 73 + 31523579 = 31523652
  • 113 + 31523539 = 31523652
  • 131 + 31523521 = 31523652
  • 179 + 31523473 = 31523652
  • 191 + 31523461 = 31523652

Showing the first eight; more decompositions exist.
