Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989530, here are decompositions:

23 + 989507 = 989530
53 + 989477 = 989530
89 + 989441 = 989530
107 + 989423 = 989530
149 + 989381 = 989530
251 + 989279 = 989530
281 + 989249 = 989530
359 + 989171 = 989530

Showing the first eight; more decompositions exist.
