Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463970, here are decompositions:

7 + 31463963 = 31463970
11 + 31463959 = 31463970
29 + 31463941 = 31463970
59 + 31463911 = 31463970
61 + 31463909 = 31463970
73 + 31463897 = 31463970
79 + 31463891 = 31463970
113 + 31463857 = 31463970

Showing the first eight; more decompositions exist.
