Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636630, here are decompositions:

3 + 8636627 = 8636630
31 + 8636599 = 8636630
43 + 8636587 = 8636630
97 + 8636533 = 8636630
109 + 8636521 = 8636630
139 + 8636491 = 8636630
157 + 8636473 = 8636630
181 + 8636449 = 8636630

Showing the first eight; more decompositions exist.
