Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493316, here are decompositions:

67 + 31493249 = 31493316
163 + 31493153 = 31493316
233 + 31493083 = 31493316
263 + 31493053 = 31493316
269 + 31493047 = 31493316
277 + 31493039 = 31493316
307 + 31493009 = 31493316
353 + 31492963 = 31493316

Showing the first eight; more decompositions exist.
