Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450894, here are decompositions:

  • 3 + 31450891 = 31450894
  • 47 + 31450847 = 31450894
  • 53 + 31450841 = 31450894
  • 71 + 31450823 = 31450894
  • 107 + 31450787 = 31450894
  • 113 + 31450781 = 31450894
  • 131 + 31450763 = 31450894
  • 173 + 31450721 = 31450894

Showing the first eight; more decompositions exist.
