Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624558, here are decompositions:

109 + 8624449 = 8624558
307 + 8624251 = 8624558
337 + 8624221 = 8624558
367 + 8624191 = 8624558
379 + 8624179 = 8624558
421 + 8624137 = 8624558
457 + 8624101 = 8624558
499 + 8624059 = 8624558

Showing the first eight; more decompositions exist.
