Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999250, here are decompositions:

11 + 999239 = 999250
17 + 999233 = 999250
29 + 999221 = 999250
101 + 999149 = 999250
149 + 999101 = 999250
167 + 999083 = 999250
227 + 999023 = 999250
281 + 998969 = 999250

Showing the first eight; more decompositions exist.
