Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618508, here are decompositions:

7 + 8618501 = 8618508
29 + 8618479 = 8618508
79 + 8618429 = 8618508
131 + 8618377 = 8618508
179 + 8618329 = 8618508
181 + 8618327 = 8618508
191 + 8618317 = 8618508
211 + 8618297 = 8618508

Showing the first eight; more decompositions exist.
