Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560736, here are decompositions:

  • 5 + 31560731 = 31560736
  • 17 + 31560719 = 31560736
  • 23 + 31560713 = 31560736
  • 47 + 31560689 = 31560736
  • 59 + 31560677 = 31560736
  • 89 + 31560647 = 31560736
  • 107 + 31560629 = 31560736
  • 149 + 31560587 = 31560736

Showing the first eight; more decompositions exist.
