Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618608, here are decompositions:

17 + 8618591 = 8618608
41 + 8618567 = 8618608
107 + 8618501 = 8618608
179 + 8618429 = 8618608
269 + 8618339 = 8618608
281 + 8618327 = 8618608
311 + 8618297 = 8618608
461 + 8618147 = 8618608

Showing the first eight; more decompositions exist.
