Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81314, here are decompositions:

  • 7 + 81307 = 81314
  • 31 + 81283 = 81314
  • 151 + 81163 = 81314
  • 157 + 81157 = 81314
  • 271 + 81043 = 81314
  • 283 + 81031 = 81314
  • 313 + 81001 = 81314
  • 397 + 80917 = 81314

Showing the first eight; more decompositions exist.
