Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465296, here are decompositions:

7 + 31465289 = 31465296
53 + 31465243 = 31465296
73 + 31465223 = 31465296
103 + 31465193 = 31465296
113 + 31465183 = 31465296
167 + 31465129 = 31465296
173 + 31465123 = 31465296
197 + 31465099 = 31465296

Showing the first eight; more decompositions exist.
