Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479478, here are decompositions:

5 + 479473 = 479478
17 + 479461 = 479478
37 + 479441 = 479478
47 + 479431 = 479478
59 + 479419 = 479478
101 + 479377 = 479478
107 + 479371 = 479478
151 + 479327 = 479478

Showing the first eight; more decompositions exist.
