Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989474, here are decompositions:

7 + 989467 = 989474
97 + 989377 = 989474
127 + 989347 = 989474
151 + 989323 = 989474
181 + 989293 = 989474
223 + 989251 = 989474
463 + 989011 = 989474
523 + 988951 = 989474

Showing the first eight; more decompositions exist.
