Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529946, here are decompositions:

  • 13 + 31529933 = 31529946
  • 23 + 31529923 = 31529946
  • 47 + 31529899 = 31529946
  • 103 + 31529843 = 31529946
  • 127 + 31529819 = 31529946
  • 163 + 31529783 = 31529946
  • 197 + 31529749 = 31529946
  • 229 + 31529717 = 31529946

Showing the first eight; more decompositions exist.
