Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989470, here are decompositions:

3 + 989467 = 989470
29 + 989441 = 989470
47 + 989423 = 989470
59 + 989411 = 989470
89 + 989381 = 989470
149 + 989321 = 989470
191 + 989279 = 989470
239 + 989231 = 989470

Showing the first eight; more decompositions exist.
