Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624458, here are decompositions:

131 + 8624327 = 8624458
191 + 8624267 = 8624458
257 + 8624201 = 8624458
281 + 8624177 = 8624458
317 + 8624141 = 8624458
347 + 8624111 = 8624458
431 + 8624027 = 8624458
449 + 8624009 = 8624458

Showing the first eight; more decompositions exist.
