Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620770, here are decompositions:

  • 13 + 8620757 = 8620770
  • 23 + 8620747 = 8620770
  • 31 + 8620739 = 8620770
  • 43 + 8620727 = 8620770
  • 47 + 8620723 = 8620770
  • 79 + 8620691 = 8620770
  • 83 + 8620687 = 8620770
  • 97 + 8620673 = 8620770

Showing the first eight; more decompositions exist.
