Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477640, here are decompositions:

3 + 477637 = 477640
17 + 477623 = 477640
47 + 477593 = 477640
83 + 477557 = 477640
89 + 477551 = 477640
101 + 477539 = 477640
179 + 477461 = 477640
257 + 477383 = 477640

Showing the first eight; more decompositions exist.
