Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607974, here are decompositions:

3 + 31607971 = 31607974
5 + 31607969 = 31607974
53 + 31607921 = 31607974
71 + 31607903 = 31607974
107 + 31607867 = 31607974
191 + 31607783 = 31607974
227 + 31607747 = 31607974
257 + 31607717 = 31607974

Showing the first eight; more decompositions exist.
