Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668508, here are decompositions:

7 + 8668501 = 8668508
19 + 8668489 = 8668508
127 + 8668381 = 8668508
139 + 8668369 = 8668508
151 + 8668357 = 8668508
229 + 8668279 = 8668508
241 + 8668267 = 8668508
307 + 8668201 = 8668508

Showing the first eight; more decompositions exist.
