Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477326, here are decompositions:

5 + 31477321 = 31477326
37 + 31477289 = 31477326
113 + 31477213 = 31477326
163 + 31477163 = 31477326
227 + 31477099 = 31477326
263 + 31477063 = 31477326
269 + 31477057 = 31477326
367 + 31476959 = 31477326

Showing the first eight; more decompositions exist.
