Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631894, here are decompositions:

  • 13 + 8631881 = 8631894
  • 43 + 8631851 = 8631894
  • 71 + 8631823 = 8631894
  • 107 + 8631787 = 8631894
  • 113 + 8631781 = 8631894
  • 151 + 8631743 = 8631894
  • 157 + 8631737 = 8631894
  • 181 + 8631713 = 8631894

Showing the first eight; more decompositions exist.
