Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989210, here are decompositions:

37 + 989173 = 989210
139 + 989071 = 989210
151 + 989059 = 989210
181 + 989029 = 989210
199 + 989011 = 989210
349 + 988861 = 989210
373 + 988837 = 989210
421 + 988789 = 989210

Showing the first eight; more decompositions exist.
