Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989518, here are decompositions:

11 + 989507 = 989518
41 + 989477 = 989518
107 + 989411 = 989518
137 + 989381 = 989518
191 + 989327 = 989518
197 + 989321 = 989518
239 + 989279 = 989518
269 + 989249 = 989518

Showing the first eight; more decompositions exist.
