Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481248, here are decompositions:

17 + 481231 = 481248
37 + 481211 = 481248
41 + 481207 = 481248
67 + 481181 = 481248
71 + 481177 = 481248
101 + 481147 = 481248
107 + 481141 = 481248
139 + 481109 = 481248

Showing the first eight; more decompositions exist.
