Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620788, here are decompositions:

  • 31 + 8620757 = 8620788
  • 41 + 8620747 = 8620788
  • 61 + 8620727 = 8620788
  • 67 + 8620721 = 8620788
  • 97 + 8620691 = 8620788
  • 101 + 8620687 = 8620788
  • 149 + 8620639 = 8620788
  • 151 + 8620637 = 8620788

Showing the first eight; more decompositions exist.
