Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637506, here are decompositions:

13 + 8637493 = 8637506
79 + 8637427 = 8637506
127 + 8637379 = 8637506
373 + 8637133 = 8637506
439 + 8637067 = 8637506
499 + 8637007 = 8637506
547 + 8636959 = 8637506
607 + 8636899 = 8637506

Showing the first eight; more decompositions exist.
