Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544756, here are decompositions:

  • 7 + 31544749 = 31544756
  • 37 + 31544719 = 31544756
  • 43 + 31544713 = 31544756
  • 223 + 31544533 = 31544756
  • 409 + 31544347 = 31544756
  • 433 + 31544323 = 31544756
  • 577 + 31544179 = 31544756
  • 769 + 31543987 = 31544756

Showing the first eight; more decompositions exist.
