Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477780, here are decompositions:

11 + 477769 = 477780
13 + 477767 = 477780
41 + 477739 = 477780
53 + 477727 = 477780
59 + 477721 = 477780
103 + 477677 = 477780
109 + 477671 = 477780
157 + 477623 = 477780

Showing the first eight; more decompositions exist.
