Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645352, here are decompositions:

11 + 8645341 = 8645352
59 + 8645293 = 8645352
71 + 8645281 = 8645352
83 + 8645269 = 8645352
109 + 8645243 = 8645352
113 + 8645239 = 8645352
173 + 8645179 = 8645352
211 + 8645141 = 8645352

Showing the first eight; more decompositions exist.
