Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460070, here are decompositions:

7 + 31460063 = 31460070
17 + 31460053 = 31460070
53 + 31460017 = 31460070
71 + 31459999 = 31460070
107 + 31459963 = 31460070
139 + 31459931 = 31460070
179 + 31459891 = 31460070
211 + 31459859 = 31460070

Showing the first eight; more decompositions exist.
