Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001970, here are decompositions:

17 + 1001953 = 1001970
23 + 1001947 = 1001970
29 + 1001941 = 1001970
37 + 1001933 = 1001970
59 + 1001911 = 1001970
131 + 1001839 = 1001970
139 + 1001831 = 1001970
149 + 1001821 = 1001970

Showing the first eight; more decompositions exist.
