Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990252, here are decompositions:

13 + 990239 = 990252
41 + 990211 = 990252
71 + 990181 = 990252
73 + 990179 = 990252
83 + 990169 = 990252
89 + 990163 = 990252
101 + 990151 = 990252
199 + 990053 = 990252

Showing the first eight; more decompositions exist.
