Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587934, here are decompositions:

11 + 31587923 = 31587934
23 + 31587911 = 31587934
41 + 31587893 = 31587934
167 + 31587767 = 31587934
197 + 31587737 = 31587934
227 + 31587707 = 31587934
233 + 31587701 = 31587934
311 + 31587623 = 31587934

Showing the first eight; more decompositions exist.
