Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481228, here are decompositions:

17 + 481211 = 481228
29 + 481199 = 481228
47 + 481181 = 481228
71 + 481157 = 481228
131 + 481097 = 481228
227 + 481001 = 481228
239 + 480989 = 481228
269 + 480959 = 481228

Showing the first eight; more decompositions exist.
