Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477612, here are decompositions:

29 + 31477583 = 31477612
41 + 31477571 = 31477612
59 + 31477553 = 31477612
233 + 31477379 = 31477612
263 + 31477349 = 31477612
311 + 31477301 = 31477612
431 + 31477181 = 31477612
449 + 31477163 = 31477612

Showing the first eight; more decompositions exist.
