Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479820, here are decompositions:

7 + 479813 = 479820
23 + 479797 = 479820
37 + 479783 = 479820
43 + 479777 = 479820
59 + 479761 = 479820
67 + 479753 = 479820
71 + 479749 = 479820
181 + 479639 = 479820

Showing the first eight; more decompositions exist.
