Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500934, here are decompositions:

11 + 31500923 = 31500934
71 + 31500863 = 31500934
137 + 31500797 = 31500934
167 + 31500767 = 31500934
197 + 31500737 = 31500934
233 + 31500701 = 31500934
431 + 31500503 = 31500934
557 + 31500377 = 31500934

Showing the first eight; more decompositions exist.
