Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451674, here are decompositions:

  • 17 + 31451657 = 31451674
  • 113 + 31451561 = 31451674
  • 503 + 31451171 = 31451674
  • 563 + 31451111 = 31451674
  • 641 + 31451033 = 31451674
  • 677 + 31450997 = 31451674
  • 827 + 31450847 = 31451674
  • 887 + 31450787 = 31451674

Showing the first eight; more decompositions exist.
