Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657618, here are decompositions:

7 + 8657611 = 8657618
61 + 8657557 = 8657618
157 + 8657461 = 8657618
241 + 8657377 = 8657618
379 + 8657239 = 8657618
397 + 8657221 = 8657618
457 + 8657161 = 8657618
577 + 8657041 = 8657618

Showing the first eight; more decompositions exist.
