Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574914, here are decompositions:

  • 3 + 31574911 = 31574914
  • 23 + 31574891 = 31574914
  • 53 + 31574861 = 31574914
  • 101 + 31574813 = 31574914
  • 167 + 31574747 = 31574914
  • 191 + 31574723 = 31574914
  • 227 + 31574687 = 31574914
  • 233 + 31574681 = 31574914

Showing the first eight; more decompositions exist.
