Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989974, here are decompositions:

3 + 989971 = 989974
23 + 989951 = 989974
53 + 989921 = 989974
101 + 989873 = 989974
137 + 989837 = 989974
191 + 989783 = 989974
197 + 989777 = 989974
311 + 989663 = 989974

Showing the first eight; more decompositions exist.
