Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637572, here are decompositions:

79 + 8637493 = 8637572
193 + 8637379 = 8637572
199 + 8637373 = 8637572
271 + 8637301 = 8637572
283 + 8637289 = 8637572
409 + 8637163 = 8637572
421 + 8637151 = 8637572
439 + 8637133 = 8637572

Showing the first eight; more decompositions exist.
