Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479220, here are decompositions:

11 + 479209 = 479220
19 + 479201 = 479220
29 + 479191 = 479220
31 + 479189 = 479220
67 + 479153 = 479220
73 + 479147 = 479220
83 + 479137 = 479220
89 + 479131 = 479220

Showing the first eight; more decompositions exist.
