Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989212, here are decompositions:

41 + 989171 = 989212
89 + 989123 = 989212
113 + 989099 = 989212
131 + 989081 = 989212
233 + 988979 = 989212
311 + 988901 = 989212
353 + 988859 = 989212
383 + 988829 = 989212

Showing the first eight; more decompositions exist.
