Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624998, here are decompositions:

17 + 8624981 = 8624998
191 + 8624807 = 8624998
227 + 8624771 = 8624998
281 + 8624717 = 8624998
491 + 8624507 = 8624998
521 + 8624477 = 8624998
761 + 8624237 = 8624998
797 + 8624201 = 8624998

Showing the first eight; more decompositions exist.
