Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 966990, here are decompositions:

19 + 966971 = 966990
29 + 966961 = 966990
53 + 966937 = 966990
67 + 966923 = 966990
71 + 966919 = 966990
83 + 966907 = 966990
97 + 966893 = 966990
107 + 966883 = 966990

Showing the first eight; more decompositions exist.
