Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618416, here are decompositions:

3 + 8618413 = 8618416
29 + 8618387 = 8618416
89 + 8618327 = 8618416
173 + 8618243 = 8618416
179 + 8618237 = 8618416
269 + 8618147 = 8618416
353 + 8618063 = 8618416
383 + 8618033 = 8618416

Showing the first eight; more decompositions exist.
