Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637618, here are decompositions:

7 + 8637611 = 8637618
97 + 8637521 = 8637618
109 + 8637509 = 8637618
127 + 8637491 = 8637618
137 + 8637481 = 8637618
151 + 8637467 = 8637618
167 + 8637451 = 8637618
191 + 8637427 = 8637618

Showing the first eight; more decompositions exist.
