Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729970, here are decompositions:

31 + 8729939 = 8729970
47 + 8729923 = 8729970
83 + 8729887 = 8729970
89 + 8729881 = 8729970
101 + 8729869 = 8729970
103 + 8729867 = 8729970
131 + 8729839 = 8729970
149 + 8729821 = 8729970

Showing the first eight; more decompositions exist.
