Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477434, here are decompositions:

5 + 31477429 = 31477434
7 + 31477427 = 31477434
11 + 31477423 = 31477434
83 + 31477351 = 31477434
113 + 31477321 = 31477434
227 + 31477207 = 31477434
271 + 31477163 = 31477434
293 + 31477141 = 31477434

Showing the first eight; more decompositions exist.
