Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 480990, here are decompositions:

11 + 480979 = 480990
23 + 480967 = 480990
31 + 480959 = 480990
53 + 480937 = 480990
61 + 480929 = 480990
71 + 480919 = 480990
79 + 480911 = 480990
109 + 480881 = 480990

Showing the first eight; more decompositions exist.
