Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 485280, here are decompositions:

17 + 485263 = 485280
71 + 485209 = 485280
73 + 485207 = 485280
79 + 485201 = 485280
109 + 485171 = 485280
113 + 485167 = 485280
149 + 485131 = 485280
157 + 485123 = 485280

Showing the first eight; more decompositions exist.
