Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999252, here are decompositions:

13 + 999239 = 999252
19 + 999233 = 999252
31 + 999221 = 999252
53 + 999199 = 999252
71 + 999181 = 999252
83 + 999169 = 999252
103 + 999149 = 999252
151 + 999101 = 999252

Showing the first eight; more decompositions exist.
