Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544860, here are decompositions:

  • 3 + 31544857 = 31544860
  • 41 + 31544819 = 31544860
  • 89 + 31544771 = 31544860
  • 101 + 31544759 = 31544860
  • 317 + 31544543 = 31544860
  • 443 + 31544417 = 31544860
  • 467 + 31544393 = 31544860
  • 563 + 31544297 = 31544860

Showing the first eight; more decompositions exist.
