Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596642, here are decompositions:

  • 5 + 31596637 = 31596642
  • 29 + 31596613 = 31596642
  • 31 + 31596611 = 31596642
  • 59 + 31596583 = 31596642
  • 71 + 31596571 = 31596642
  • 89 + 31596553 = 31596642
  • 101 + 31596541 = 31596642
  • 131 + 31596511 = 31596642

Showing the first eight; more decompositions exist.
