Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656472, here are decompositions:

3 + 8656469 = 8656472
61 + 8656411 = 8656472
73 + 8656399 = 8656472
79 + 8656393 = 8656472
103 + 8656369 = 8656472
109 + 8656363 = 8656472
151 + 8656321 = 8656472
193 + 8656279 = 8656472

Showing the first eight; more decompositions exist.
