Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739618, here are decompositions:

11 + 8739607 = 8739618
89 + 8739529 = 8739618
127 + 8739491 = 8739618
137 + 8739481 = 8739618
227 + 8739391 = 8739618
229 + 8739389 = 8739618
269 + 8739349 = 8739618
281 + 8739337 = 8739618

Showing the first eight; more decompositions exist.
