Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989170, here are decompositions:

47 + 989123 = 989170
71 + 989099 = 989170
89 + 989081 = 989170
191 + 988979 = 989170
233 + 988937 = 989170
269 + 988901 = 989170
293 + 988877 = 989170
311 + 988859 = 989170

Showing the first eight; more decompositions exist.
