Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645032, here are decompositions:

3 + 8645029 = 8645032
23 + 8645009 = 8645032
41 + 8644991 = 8645032
83 + 8644949 = 8645032
113 + 8644919 = 8645032
233 + 8644799 = 8645032
251 + 8644781 = 8645032
281 + 8644751 = 8645032

Showing the first eight; more decompositions exist.
