Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657644, here are decompositions:

5 + 8657639 = 8657644
11 + 8657633 = 8657644
131 + 8657513 = 8657644
257 + 8657387 = 8657644
263 + 8657381 = 8657644
311 + 8657333 = 8657644
353 + 8657291 = 8657644
521 + 8657123 = 8657644

Showing the first eight; more decompositions exist.
