Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989738, here are decompositions:

19 + 989719 = 989738
67 + 989671 = 989738
97 + 989641 = 989738
109 + 989629 = 989738
157 + 989581 = 989738
181 + 989557 = 989738
271 + 989467 = 989738
397 + 989341 = 989738

Showing the first eight; more decompositions exist.
