Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611618, here are decompositions:

5 + 8611613 = 8611618
17 + 8611601 = 8611618
89 + 8611529 = 8611618
131 + 8611487 = 8611618
179 + 8611439 = 8611618
269 + 8611349 = 8611618
311 + 8611307 = 8611618
317 + 8611301 = 8611618

Showing the first eight; more decompositions exist.
