Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645232, here are decompositions:

53 + 8645179 = 8645232
109 + 8645123 = 8645232
151 + 8645081 = 8645232
179 + 8645053 = 8645232
223 + 8645009 = 8645232
241 + 8644991 = 8645232
269 + 8644963 = 8645232
283 + 8644949 = 8645232

Showing the first eight; more decompositions exist.
