Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477980, here are decompositions:

3 + 477977 = 477980
7 + 477973 = 477980
67 + 477913 = 477980
157 + 477823 = 477980
211 + 477769 = 477980
241 + 477739 = 477980
409 + 477571 = 477980
457 + 477523 = 477980

Showing the first eight; more decompositions exist.
