Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710638, here are decompositions:

5 + 8710633 = 8710638
7 + 8710631 = 8710638
11 + 8710627 = 8710638
17 + 8710621 = 8710638
29 + 8710609 = 8710638
67 + 8710571 = 8710638
71 + 8710567 = 8710638
109 + 8710529 = 8710638

Showing the first eight; more decompositions exist.
