Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718490, here are decompositions:

  • 3 + 8718487 = 8718490
  • 29 + 8718461 = 8718490
  • 59 + 8718431 = 8718490
  • 71 + 8718419 = 8718490
  • 83 + 8718407 = 8718490
  • 89 + 8718401 = 8718490
  • 113 + 8718377 = 8718490
  • 239 + 8718251 = 8718490

Showing the first eight; more decompositions exist.
