Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465356, here are decompositions:

47 + 31465309 = 31465356
67 + 31465289 = 31465356
113 + 31465243 = 31465356
163 + 31465193 = 31465356
173 + 31465183 = 31465356
179 + 31465177 = 31465356
227 + 31465129 = 31465356
233 + 31465123 = 31465356

Showing the first eight; more decompositions exist.
