Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541316, here are decompositions:

19 + 31541297 = 31541316
47 + 31541269 = 31541316
73 + 31541243 = 31541316
83 + 31541233 = 31541316
137 + 31541179 = 31541316
199 + 31541117 = 31541316
269 + 31541047 = 31541316
277 + 31541039 = 31541316

Showing the first eight; more decompositions exist.
