Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623680, here are decompositions:

  • 19 + 8623661 = 8623680
  • 29 + 8623651 = 8623680
  • 41 + 8623639 = 8623680
  • 59 + 8623621 = 8623680
  • 61 + 8623619 = 8623680
  • 97 + 8623583 = 8623680
  • 101 + 8623579 = 8623680
  • 151 + 8623529 = 8623680

Showing the first eight; more decompositions exist.
