Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981070, here are decompositions:

3 + 981067 = 981070
47 + 981023 = 981070
53 + 981017 = 981070
59 + 981011 = 981070
71 + 980999 = 981070
107 + 980963 = 981070
113 + 980957 = 981070
149 + 980921 = 981070

Showing the first eight; more decompositions exist.
