Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657636, here are decompositions:

3 + 8657633 = 8657636
7 + 8657629 = 8657636
67 + 8657569 = 8657636
73 + 8657563 = 8657636
79 + 8657557 = 8657636
103 + 8657533 = 8657636
313 + 8657323 = 8657636
397 + 8657239 = 8657636

Showing the first eight; more decompositions exist.
