Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636658, here are decompositions:

11 + 8636647 = 8636658
31 + 8636627 = 8636658
59 + 8636599 = 8636658
67 + 8636591 = 8636658
71 + 8636587 = 8636658
109 + 8636549 = 8636658
137 + 8636521 = 8636658
167 + 8636491 = 8636658

Showing the first eight; more decompositions exist.
