Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646588, here are decompositions:

7 + 8646581 = 8646588
17 + 8646571 = 8646588
29 + 8646559 = 8646588
59 + 8646529 = 8646588
101 + 8646487 = 8646588
109 + 8646479 = 8646588
131 + 8646457 = 8646588
199 + 8646389 = 8646588

Showing the first eight; more decompositions exist.
