Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638252, here are decompositions:

5 + 8638247 = 8638252
11 + 8638241 = 8638252
23 + 8638229 = 8638252
53 + 8638199 = 8638252
101 + 8638151 = 8638252
113 + 8638139 = 8638252
131 + 8638121 = 8638252
191 + 8638061 = 8638252

Showing the first eight; more decompositions exist.
