Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541676, here are decompositions:

  • 17 + 31541659 = 31541676
  • 43 + 31541633 = 31541676
  • 79 + 31541597 = 31541676
  • 107 + 31541569 = 31541676
  • 113 + 31541563 = 31541676
  • 149 + 31541527 = 31541676
  • 167 + 31541509 = 31541676
  • 193 + 31541483 = 31541676

Showing the first eight; more decompositions exist.
