Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704638, here are decompositions:

17 + 8704621 = 8704638
29 + 8704609 = 8704638
31 + 8704607 = 8704638
37 + 8704601 = 8704638
71 + 8704567 = 8704638
79 + 8704559 = 8704638
139 + 8704499 = 8704638
157 + 8704481 = 8704638

Showing the first eight; more decompositions exist.
