Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732490, here are decompositions:

  • 17 + 8732473 = 8732490
  • 29 + 8732461 = 8732490
  • 43 + 8732447 = 8732490
  • 59 + 8732431 = 8732490
  • 61 + 8732429 = 8732490
  • 73 + 8732417 = 8732490
  • 79 + 8732411 = 8732490
  • 127 + 8732363 = 8732490

Showing the first eight; more decompositions exist.
