Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641508, here are decompositions:

37 + 8641471 = 8641508
79 + 8641429 = 8641508
157 + 8641351 = 8641508
181 + 8641327 = 8641508
199 + 8641309 = 8641508
277 + 8641231 = 8641508
541 + 8640967 = 8641508
619 + 8640889 = 8641508

Showing the first eight; more decompositions exist.
