Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586612, here are decompositions:

  • 103 + 31586509 = 31586612
  • 139 + 31586473 = 31586612
  • 151 + 31586461 = 31586612
  • 331 + 31586281 = 31586612
  • 709 + 31585903 = 31586612
  • 829 + 31585783 = 31586612
  • 1033 + 31585579 = 31586612
  • 1063 + 31585549 = 31586612

Showing the first eight; more decompositions exist.
