Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620650, here are decompositions:

  • 11 + 8620639 = 8620650
  • 13 + 8620637 = 8620650
  • 19 + 8620631 = 8620650
  • 29 + 8620621 = 8620650
  • 47 + 8620603 = 8620650
  • 61 + 8620589 = 8620650
  • 79 + 8620571 = 8620650
  • 83 + 8620567 = 8620650

Showing the first eight; more decompositions exist.
