Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728622, here are decompositions:

  • 13 + 8728609 = 8728622
  • 31 + 8728591 = 8728622
  • 43 + 8728579 = 8728622
  • 73 + 8728549 = 8728622
  • 109 + 8728513 = 8728622
  • 139 + 8728483 = 8728622
  • 151 + 8728471 = 8728622
  • 241 + 8728381 = 8728622

Showing the first eight; more decompositions exist.
