Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641466, here are decompositions:

13 + 8641453 = 8641466
37 + 8641429 = 8641466
139 + 8641327 = 8641466
157 + 8641309 = 8641466
193 + 8641273 = 8641466
373 + 8641093 = 8641466
499 + 8640967 = 8641466
577 + 8640889 = 8641466

Showing the first eight; more decompositions exist.
