Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637852, here are decompositions:

5 + 8637847 = 8637852
23 + 8637829 = 8637852
31 + 8637821 = 8637852
61 + 8637791 = 8637852
73 + 8637779 = 8637852
103 + 8637749 = 8637852
151 + 8637701 = 8637852
211 + 8637641 = 8637852

Showing the first eight; more decompositions exist.
