Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631908, here are decompositions:

  • 127 + 8631781 = 8631908
  • 139 + 8631769 = 8631908
  • 409 + 8631499 = 8631908
  • 457 + 8631451 = 8631908
  • 541 + 8631367 = 8631908
  • 577 + 8631331 = 8631908
  • 601 + 8631307 = 8631908
  • 631 + 8631277 = 8631908

Showing the first eight; more decompositions exist.
