Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494676, here are decompositions:

  • 167 + 31494509 = 31494676
  • 173 + 31494503 = 31494676
  • 179 + 31494497 = 31494676
  • 197 + 31494479 = 31494676
  • 233 + 31494443 = 31494676
  • 383 + 31494293 = 31494676
  • 419 + 31494257 = 31494676
  • 557 + 31494119 = 31494676

Showing the first eight; more decompositions exist.
