Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491624, here are decompositions:

  • 13 + 491611 = 491624
  • 31 + 491593 = 491624
  • 43 + 491581 = 491624
  • 97 + 491527 = 491624
  • 127 + 491497 = 491624
  • 163 + 491461 = 491624
  • 271 + 491353 = 491624
  • 283 + 491341 = 491624

Showing the first eight; more decompositions exist.
