Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655782, here are decompositions:

13 + 8655769 = 8655782
43 + 8655739 = 8655782
61 + 8655721 = 8655782
103 + 8655679 = 8655782
151 + 8655631 = 8655782
349 + 8655433 = 8655782
379 + 8655403 = 8655782
433 + 8655349 = 8655782

Showing the first eight; more decompositions exist.
