Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475780, here are decompositions:

3 + 475777 = 475780
17 + 475763 = 475780
29 + 475751 = 475780
59 + 475721 = 475780
83 + 475697 = 475780
89 + 475691 = 475780
101 + 475679 = 475780
131 + 475649 = 475780

Showing the first eight; more decompositions exist.
