Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607950, here are decompositions:

29 + 31607921 = 31607950
41 + 31607909 = 31607950
47 + 31607903 = 31607950
53 + 31607897 = 31607950
83 + 31607867 = 31607950
167 + 31607783 = 31607950
233 + 31607717 = 31607950
263 + 31607687 = 31607950

Showing the first eight; more decompositions exist.
