Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481280, here are decompositions:

31 + 481249 = 481280
73 + 481207 = 481280
103 + 481177 = 481280
109 + 481171 = 481280
127 + 481153 = 481280
139 + 481141 = 481280
157 + 481123 = 481280
193 + 481087 = 481280

Showing the first eight; more decompositions exist.
