Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513794, here are decompositions:

  • 7 + 31513787 = 31513794
  • 73 + 31513721 = 31513794
  • 97 + 31513697 = 31513794
  • 101 + 31513693 = 31513794
  • 127 + 31513667 = 31513794
  • 173 + 31513621 = 31513794
  • 181 + 31513613 = 31513794
  • 233 + 31513561 = 31513794

Showing the first eight; more decompositions exist.
