Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624394, here are decompositions:

11 + 8624383 = 8624394
41 + 8624353 = 8624394
67 + 8624327 = 8624394
71 + 8624323 = 8624394
83 + 8624311 = 8624394
127 + 8624267 = 8624394
151 + 8624243 = 8624394
157 + 8624237 = 8624394

Showing the first eight; more decompositions exist.
