Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477522, here are decompositions:

173 + 31477349 = 31477522
233 + 31477289 = 31477522
359 + 31477163 = 31477522
443 + 31477079 = 31477522
563 + 31476959 = 31477522
641 + 31476881 = 31477522
701 + 31476821 = 31477522
911 + 31476611 = 31477522

Showing the first eight; more decompositions exist.
