Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477666, here are decompositions:

83 + 31477583 = 31477666
89 + 31477577 = 31477666
113 + 31477553 = 31477666
239 + 31477427 = 31477666
317 + 31477349 = 31477666
503 + 31477163 = 31477666
587 + 31477079 = 31477666
599 + 31477067 = 31477666

Showing the first eight; more decompositions exist.
