Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529950, here are decompositions:

17 + 31529933 = 31529950
59 + 31529891 = 31529950
107 + 31529843 = 31529950
131 + 31529819 = 31529950
167 + 31529783 = 31529950
233 + 31529717 = 31529950
269 + 31529681 = 31529950
281 + 31529669 = 31529950

Showing the first eight; more decompositions exist.
