Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618494, here are decompositions:

11 + 8618483 = 8618494
107 + 8618387 = 8618494
167 + 8618327 = 8618494
197 + 8618297 = 8618494
251 + 8618243 = 8618494
257 + 8618237 = 8618494
281 + 8618213 = 8618494
347 + 8618147 = 8618494

Showing the first eight; more decompositions exist.
