Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989228, here are decompositions:

109 + 989119 = 989228
157 + 989071 = 989228
199 + 989029 = 989228
277 + 988951 = 989228
367 + 988861 = 989228
379 + 988849 = 989228
439 + 988789 = 989228
547 + 988681 = 989228

Showing the first eight; more decompositions exist.
