Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518676, here are decompositions:

  • 3 + 31518673 = 31518676
  • 17 + 31518659 = 31518676
  • 23 + 31518653 = 31518676
  • 29 + 31518647 = 31518676
  • 83 + 31518593 = 31518676
  • 347 + 31518329 = 31518676
  • 389 + 31518287 = 31518676
  • 467 + 31518209 = 31518676

Showing the first eight; more decompositions exist.
