Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495316, here are decompositions:

43 + 31495273 = 31495316
103 + 31495213 = 31495316
163 + 31495153 = 31495316
199 + 31495117 = 31495316
313 + 31495003 = 31495316
337 + 31494979 = 31495316
367 + 31494949 = 31495316
373 + 31494943 = 31495316

Showing the first eight; more decompositions exist.
