Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 480820, here are decompositions:

17 + 480803 = 480820
47 + 480773 = 480820
59 + 480761 = 480820
71 + 480749 = 480820
83 + 480737 = 480820
89 + 480731 = 480820
107 + 480713 = 480820
113 + 480707 = 480820

Showing the first eight; more decompositions exist.
