Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587096, here are decompositions:

5 + 31587091 = 31587096
43 + 31587053 = 31587096
67 + 31587029 = 31587096
157 + 31586939 = 31587096
193 + 31586903 = 31587096
227 + 31586869 = 31587096
257 + 31586839 = 31587096
283 + 31586813 = 31587096

Showing the first eight; more decompositions exist.
