Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645756, here are decompositions:

37 + 8645719 = 8645756
103 + 8645653 = 8645756
109 + 8645647 = 8645756
139 + 8645617 = 8645756
307 + 8645449 = 8645756
313 + 8645443 = 8645756
349 + 8645407 = 8645756
397 + 8645359 = 8645756

Showing the first eight; more decompositions exist.
