Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529940, here are decompositions:

  • 7 + 31529933 = 31529940
  • 17 + 31529923 = 31529940
  • 41 + 31529899 = 31529940
  • 59 + 31529881 = 31529940
  • 97 + 31529843 = 31529940
  • 157 + 31529783 = 31529940
  • 191 + 31529749 = 31529940
  • 223 + 31529717 = 31529940

Showing the first eight; more decompositions exist.
