Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981252, here are decompositions:

11 + 981241 = 981252
31 + 981221 = 981252
43 + 981209 = 981252
53 + 981199 = 981252
79 + 981173 = 981252
101 + 981151 = 981252
113 + 981139 = 981252
179 + 981073 = 981252

Showing the first eight; more decompositions exist.
