Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626970, here are decompositions:

3 + 31626967 = 31626970
71 + 31626899 = 31626970
101 + 31626869 = 31626970
113 + 31626857 = 31626970
131 + 31626839 = 31626970
173 + 31626797 = 31626970
281 + 31626689 = 31626970
509 + 31626461 = 31626970

Showing the first eight; more decompositions exist.
