Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656782, here are decompositions:

23 + 8656759 = 8656782
53 + 8656729 = 8656782
61 + 8656721 = 8656782
179 + 8656603 = 8656782
193 + 8656589 = 8656782
271 + 8656511 = 8656782
283 + 8656499 = 8656782
313 + 8656469 = 8656782

Showing the first eight; more decompositions exist.
