Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626912, here are decompositions:

  • 13 + 31626899 = 31626912
  • 19 + 31626893 = 31626912
  • 29 + 31626883 = 31626912
  • 43 + 31626869 = 31626912
  • 71 + 31626841 = 31626912
  • 73 + 31626839 = 31626912
  • 223 + 31626689 = 31626912
  • 293 + 31626619 = 31626912

Showing the first eight; more decompositions exist.
