Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624378, here are decompositions:

67 + 8624311 = 8624378
127 + 8624251 = 8624378
157 + 8624221 = 8624378
199 + 8624179 = 8624378
241 + 8624137 = 8624378
277 + 8624101 = 8624378
409 + 8623969 = 8624378
439 + 8623939 = 8624378

Showing the first eight; more decompositions exist.
