Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532316, here are decompositions:

37 + 31532279 = 31532316
47 + 31532269 = 31532316
89 + 31532227 = 31532316
97 + 31532219 = 31532316
107 + 31532209 = 31532316
113 + 31532203 = 31532316
149 + 31532167 = 31532316
199 + 31532117 = 31532316

Showing the first eight; more decompositions exist.
