Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673420, here are decompositions:

  • 31 + 8673389 = 8673420
  • 43 + 8673377 = 8673420
  • 47 + 8673373 = 8673420
  • 59 + 8673361 = 8673420
  • 61 + 8673359 = 8673420
  • 73 + 8673347 = 8673420
  • 79 + 8673341 = 8673420
  • 127 + 8673293 = 8673420

Showing the first eight; more decompositions exist.
