Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624578, here are decompositions:

5 + 8624573 = 8624578
71 + 8624507 = 8624578
101 + 8624477 = 8624578
251 + 8624327 = 8624578
311 + 8624267 = 8624578
401 + 8624177 = 8624578
419 + 8624159 = 8624578
449 + 8624129 = 8624578

Showing the first eight; more decompositions exist.
