Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605314, here are decompositions:

  • 3 + 31605311 = 31605314
  • 43 + 31605271 = 31605314
  • 67 + 31605247 = 31605314
  • 241 + 31605073 = 31605314
  • 313 + 31605001 = 31605314
  • 547 + 31604767 = 31605314
  • 571 + 31604743 = 31605314
  • 673 + 31604641 = 31605314

Showing the first eight; more decompositions exist.
