Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636728, here are decompositions:

101 + 8636627 = 8636728
137 + 8636591 = 8636728
179 + 8636549 = 8636728
467 + 8636261 = 8636728
491 + 8636237 = 8636728
509 + 8636219 = 8636728
587 + 8636141 = 8636728
599 + 8636129 = 8636728

Showing the first eight; more decompositions exist.
