Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719656, here are decompositions:

53 + 8719603 = 8719656
79 + 8719577 = 8719656
83 + 8719573 = 8719656
89 + 8719567 = 8719656
107 + 8719549 = 8719656
137 + 8719519 = 8719656
173 + 8719483 = 8719656
277 + 8719379 = 8719656

Showing the first eight; more decompositions exist.
