Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618524, here are decompositions:

23 + 8618501 = 8618524
41 + 8618483 = 8618524
137 + 8618387 = 8618524
197 + 8618327 = 8618524
227 + 8618297 = 8618524
251 + 8618273 = 8618524
281 + 8618243 = 8618524
311 + 8618213 = 8618524

Showing the first eight; more decompositions exist.
