Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477552, here are decompositions:

3 + 31477549 = 31477552
173 + 31477379 = 31477552
251 + 31477301 = 31477552
263 + 31477289 = 31477552
389 + 31477163 = 31477552
593 + 31476959 = 31477552
809 + 31476743 = 31477552
929 + 31476623 = 31477552

Showing the first eight; more decompositions exist.
