Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641588, here are decompositions:

17 + 8641571 = 8641588
41 + 8641547 = 8641588
47 + 8641541 = 8641588
71 + 8641517 = 8641588
167 + 8641421 = 8641588
227 + 8641361 = 8641588
239 + 8641349 = 8641588
257 + 8641331 = 8641588

Showing the first eight; more decompositions exist.
