Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645356, here are decompositions:

3 + 8645353 = 8645356
29 + 8645327 = 8645356
89 + 8645267 = 8645356
113 + 8645243 = 8645356
233 + 8645123 = 8645356
347 + 8645009 = 8645356
443 + 8644913 = 8645356
557 + 8644799 = 8645356

Showing the first eight; more decompositions exist.
