Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636508, here are decompositions:

17 + 8636491 = 8636508
59 + 8636449 = 8636508
131 + 8636377 = 8636508
239 + 8636269 = 8636508
269 + 8636239 = 8636508
271 + 8636237 = 8636508
367 + 8636141 = 8636508
379 + 8636129 = 8636508

Showing the first eight; more decompositions exist.
