Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545462, here are decompositions:

  • 23 + 31545439 = 31545462
  • 61 + 31545401 = 31545462
  • 71 + 31545391 = 31545462
  • 83 + 31545379 = 31545462
  • 89 + 31545373 = 31545462
  • 131 + 31545331 = 31545462
  • 139 + 31545323 = 31545462
  • 163 + 31545299 = 31545462

Showing the first eight; more decompositions exist.
