Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547962, here are decompositions:

3 + 31547959 = 31547962
29 + 31547933 = 31547962
41 + 31547921 = 31547962
101 + 31547861 = 31547962
113 + 31547849 = 31547962
179 + 31547783 = 31547962
269 + 31547693 = 31547962
353 + 31547609 = 31547962

Showing the first eight; more decompositions exist.
