Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483970, here are decompositions:

13 + 31483957 = 31483970
43 + 31483927 = 31483970
109 + 31483861 = 31483970
151 + 31483819 = 31483970
163 + 31483807 = 31483970
181 + 31483789 = 31483970
211 + 31483759 = 31483970
307 + 31483663 = 31483970

Showing the first eight; more decompositions exist.
