Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530146, here are decompositions:

  • 3 + 31530143 = 31530146
  • 103 + 31530043 = 31530146
  • 223 + 31529923 = 31530146
  • 397 + 31529749 = 31530146
  • 523 + 31529623 = 31530146
  • 607 + 31529539 = 31530146
  • 733 + 31529413 = 31530146
  • 787 + 31529359 = 31530146

Showing the first eight; more decompositions exist.
