Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596784, here are decompositions:

  • 41 + 31596743 = 31596784
  • 71 + 31596713 = 31596784
  • 113 + 31596671 = 31596784
  • 173 + 31596611 = 31596784
  • 311 + 31596473 = 31596784
  • 347 + 31596437 = 31596784
  • 383 + 31596401 = 31596784
  • 467 + 31596317 = 31596784

Showing the first eight; more decompositions exist.
