Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476970, here are decompositions:

11 + 31476959 = 31476970
23 + 31476947 = 31476970
53 + 31476917 = 31476970
89 + 31476881 = 31476970
149 + 31476821 = 31476970
227 + 31476743 = 31476970
347 + 31476623 = 31476970
359 + 31476611 = 31476970

Showing the first eight; more decompositions exist.
