Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529124, here are decompositions:

  • 17 + 31529107 = 31529124
  • 37 + 31529087 = 31529124
  • 43 + 31529081 = 31529124
  • 71 + 31529053 = 31529124
  • 127 + 31528997 = 31529124
  • 131 + 31528993 = 31529124
  • 157 + 31528967 = 31529124
  • 271 + 31528853 = 31529124

Showing the first eight; more decompositions exist.
