Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477360, here are decompositions:

11 + 31477349 = 31477360
59 + 31477301 = 31477360
71 + 31477289 = 31477360
179 + 31477181 = 31477360
197 + 31477163 = 31477360
281 + 31477079 = 31477360
293 + 31477067 = 31477360
401 + 31476959 = 31477360

Showing the first eight; more decompositions exist.
