Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637832, here are decompositions:

3 + 8637829 = 8637832
11 + 8637821 = 8637832
41 + 8637791 = 8637832
53 + 8637779 = 8637832
83 + 8637749 = 8637832
131 + 8637701 = 8637832
191 + 8637641 = 8637832
311 + 8637521 = 8637832

Showing the first eight; more decompositions exist.
