Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618636, here are decompositions:

43 + 8618593 = 8618636
79 + 8618557 = 8618636
157 + 8618479 = 8618636
193 + 8618443 = 8618636
223 + 8618413 = 8618636
307 + 8618329 = 8618636
349 + 8618287 = 8618636
379 + 8618257 = 8618636

Showing the first eight; more decompositions exist.
