Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650438, here are decompositions:

  • 29 + 8650409 = 8650438
  • 47 + 8650391 = 8650438
  • 131 + 8650307 = 8650438
  • 179 + 8650259 = 8650438
  • 227 + 8650211 = 8650438
  • 317 + 8650121 = 8650438
  • 509 + 8649929 = 8650438
  • 557 + 8649881 = 8650438

Showing the first eight; more decompositions exist.
