Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460970, here are decompositions:

19 + 31460951 = 31460970
41 + 31460929 = 31460970
43 + 31460927 = 31460970
53 + 31460917 = 31460970
97 + 31460873 = 31460970
131 + 31460839 = 31460970
137 + 31460833 = 31460970
139 + 31460831 = 31460970

Showing the first eight; more decompositions exist.
