Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639708, here are decompositions:

61 + 8639647 = 8639708
109 + 8639599 = 8639708
157 + 8639551 = 8639708
307 + 8639401 = 8639708
409 + 8639299 = 8639708
457 + 8639251 = 8639708
547 + 8639161 = 8639708
577 + 8639131 = 8639708

Showing the first eight; more decompositions exist.
