Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624428, here are decompositions:

101 + 8624327 = 8624428
179 + 8624249 = 8624428
191 + 8624237 = 8624428
227 + 8624201 = 8624428
251 + 8624177 = 8624428
269 + 8624159 = 8624428
317 + 8624111 = 8624428
401 + 8624027 = 8624428

Showing the first eight; more decompositions exist.
