Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479442, here are decompositions:

11 + 479431 = 479442
13 + 479429 = 479442
23 + 479419 = 479442
71 + 479371 = 479442
179 + 479263 = 479442
199 + 479243 = 479442
211 + 479231 = 479442
233 + 479209 = 479442

Showing the first eight; more decompositions exist.
