Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642508, here are decompositions:

19 + 8642489 = 8642508
41 + 8642467 = 8642508
59 + 8642449 = 8642508
79 + 8642429 = 8642508
179 + 8642329 = 8642508
227 + 8642281 = 8642508
271 + 8642237 = 8642508
311 + 8642197 = 8642508

Showing the first eight; more decompositions exist.
