Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624434, here are decompositions:

41 + 8624393 = 8624434
107 + 8624327 = 8624434
167 + 8624267 = 8624434
191 + 8624243 = 8624434
197 + 8624237 = 8624434
233 + 8624201 = 8624434
251 + 8624183 = 8624434
257 + 8624177 = 8624434

Showing the first eight; more decompositions exist.
