Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477666, here are decompositions:

29 + 477637 = 477666
43 + 477623 = 477666
47 + 477619 = 477666
73 + 477593 = 477666
89 + 477577 = 477666
109 + 477557 = 477666
113 + 477553 = 477666
127 + 477539 = 477666

Showing the first eight; more decompositions exist.
