Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624386, here are decompositions:

3 + 8624383 = 8624386
59 + 8624327 = 8624386
137 + 8624249 = 8624386
149 + 8624237 = 8624386
227 + 8624159 = 8624386
233 + 8624153 = 8624386
257 + 8624129 = 8624386
359 + 8624027 = 8624386

Showing the first eight; more decompositions exist.
