Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645056, here are decompositions:

3 + 8645053 = 8645056
47 + 8645009 = 8645056
107 + 8644949 = 8645056
137 + 8644919 = 8645056
257 + 8644799 = 8645056
353 + 8644703 = 8645056
449 + 8644607 = 8645056
503 + 8644553 = 8645056

Showing the first eight; more decompositions exist.
