Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989512, here are decompositions:

5 + 989507 = 989512
71 + 989441 = 989512
89 + 989423 = 989512
101 + 989411 = 989512
131 + 989381 = 989512
191 + 989321 = 989512
233 + 989279 = 989512
263 + 989249 = 989512

Showing the first eight; more decompositions exist.
