Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631826, here are decompositions:

  • 3 + 8631823 = 8631826
  • 23 + 8631803 = 8631826
  • 83 + 8631743 = 8631826
  • 89 + 8631737 = 8631826
  • 113 + 8631713 = 8631826
  • 167 + 8631659 = 8631826
  • 197 + 8631629 = 8631826
  • 227 + 8631599 = 8631826

Showing the first eight; more decompositions exist.
