Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587676, here are decompositions:

17 + 31587659 = 31587676
53 + 31587623 = 31587676
59 + 31587617 = 31587676
89 + 31587587 = 31587676
149 + 31587527 = 31587676
167 + 31587509 = 31587676
179 + 31587497 = 31587676
269 + 31587407 = 31587676

Showing the first eight; more decompositions exist.
