Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987618, here are decompositions:

11 + 987607 = 987618
19 + 987599 = 987618
31 + 987587 = 987618
59 + 987559 = 987618
109 + 987509 = 987618
127 + 987491 = 987618
227 + 987391 = 987618
257 + 987361 = 987618

Showing the first eight; more decompositions exist.
