Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465376, here are decompositions:

13 + 31465363 = 31465376
67 + 31465309 = 31465376
193 + 31465183 = 31465376
199 + 31465177 = 31465376
223 + 31465153 = 31465376
277 + 31465099 = 31465376
307 + 31465069 = 31465376
337 + 31465039 = 31465376

Showing the first eight; more decompositions exist.
