Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627730, here are decompositions:

17 + 8627713 = 8627730
29 + 8627701 = 8627730
31 + 8627699 = 8627730
37 + 8627693 = 8627730
103 + 8627627 = 8627730
113 + 8627617 = 8627730
127 + 8627603 = 8627730
149 + 8627581 = 8627730

Showing the first eight; more decompositions exist.
