Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465458, here are decompositions:

7 + 31465451 = 31465458
41 + 31465417 = 31465458
67 + 31465391 = 31465458
137 + 31465321 = 31465458
149 + 31465309 = 31465458
281 + 31465177 = 31465458
347 + 31465111 = 31465458
359 + 31465099 = 31465458

Showing the first eight; more decompositions exist.
