Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479778, here are decompositions:

7 + 479771 = 479778
17 + 479761 = 479778
29 + 479749 = 479778
139 + 479639 = 479778
149 + 479629 = 479778
179 + 479599 = 479778
197 + 479581 = 479778
269 + 479509 = 479778

Showing the first eight; more decompositions exist.
