Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636660, here are decompositions:

13 + 8636647 = 8636660
61 + 8636599 = 8636660
73 + 8636587 = 8636660
79 + 8636581 = 8636660
127 + 8636533 = 8636660
139 + 8636521 = 8636660
211 + 8636449 = 8636660
271 + 8636389 = 8636660

Showing the first eight; more decompositions exist.
