Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477462, here are decompositions:

83 + 31477379 = 31477462
113 + 31477349 = 31477462
173 + 31477289 = 31477462
281 + 31477181 = 31477462
383 + 31477079 = 31477462
503 + 31476959 = 31477462
641 + 31476821 = 31477462
719 + 31476743 = 31477462

Showing the first eight; more decompositions exist.
