Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539914, here are decompositions:

  • 13 + 31539901 = 31539914
  • 97 + 31539817 = 31539914
  • 151 + 31539763 = 31539914
  • 157 + 31539757 = 31539914
  • 271 + 31539643 = 31539914
  • 331 + 31539583 = 31539914
  • 547 + 31539367 = 31539914
  • 577 + 31539337 = 31539914

Showing the first eight; more decompositions exist.
