Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636578, here are decompositions:

29 + 8636549 = 8636578
191 + 8636387 = 8636578
317 + 8636261 = 8636578
359 + 8636219 = 8636578
449 + 8636129 = 8636578
491 + 8636087 = 8636578
521 + 8636057 = 8636578
557 + 8636021 = 8636578

Showing the first eight; more decompositions exist.
