Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625806, here are decompositions:

19 + 8625787 = 8625806
73 + 8625733 = 8625806
97 + 8625709 = 8625806
157 + 8625649 = 8625806
313 + 8625493 = 8625806
457 + 8625349 = 8625806
463 + 8625343 = 8625806
577 + 8625229 = 8625806

Showing the first eight; more decompositions exist.
