Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534788, here are decompositions:

  • 31 + 31534757 = 31534788
  • 37 + 31534751 = 31534788
  • 59 + 31534729 = 31534788
  • 79 + 31534709 = 31534788
  • 97 + 31534691 = 31534788
  • 137 + 31534651 = 31534788
  • 151 + 31534637 = 31534788
  • 157 + 31534631 = 31534788

Showing the first eight; more decompositions exist.
