Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645528, here are decompositions:

37 + 8645491 = 8645528
79 + 8645449 = 8645528
97 + 8645431 = 8645528
271 + 8645257 = 8645528
349 + 8645179 = 8645528
457 + 8645071 = 8645528
499 + 8645029 = 8645528
571 + 8644957 = 8645528

Showing the first eight; more decompositions exist.
