Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989218, here are decompositions:

47 + 989171 = 989218
137 + 989081 = 989218
239 + 988979 = 989218
281 + 988937 = 989218
317 + 988901 = 989218
359 + 988859 = 989218
389 + 988829 = 989218
491 + 988727 = 989218

Showing the first eight; more decompositions exist.
