Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614340, here are decompositions:

  • 113 + 31614227 = 31614340
  • 167 + 31614173 = 31614340
  • 179 + 31614161 = 31614340
  • 269 + 31614071 = 31614340
  • 479 + 31613861 = 31614340
  • 521 + 31613819 = 31614340
  • 557 + 31613783 = 31614340
  • 701 + 31613639 = 31614340

Showing the first eight; more decompositions exist.
