Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999288, here are decompositions:

19 + 999269 = 999288
67 + 999221 = 999288
71 + 999217 = 999288
89 + 999199 = 999288
107 + 999181 = 999288
139 + 999149 = 999288
197 + 999091 = 999288
239 + 999049 = 999288

Showing the first eight; more decompositions exist.
