Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645612, here are decompositions:

163 + 8645449 = 8645612
181 + 8645431 = 8645612
271 + 8645341 = 8645612
331 + 8645281 = 8645612
373 + 8645239 = 8645612
433 + 8645179 = 8645612
499 + 8645113 = 8645612
541 + 8645071 = 8645612

Showing the first eight; more decompositions exist.
