Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470964, here are decompositions:

11 + 31470953 = 31470964
23 + 31470941 = 31470964
47 + 31470917 = 31470964
53 + 31470911 = 31470964
101 + 31470863 = 31470964
131 + 31470833 = 31470964
137 + 31470827 = 31470964
263 + 31470701 = 31470964

Showing the first eight; more decompositions exist.
