Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481128, here are decompositions:

5 + 481123 = 481128
19 + 481109 = 481128
31 + 481097 = 481128
41 + 481087 = 481128
61 + 481067 = 481128
107 + 481021 = 481128
127 + 481001 = 481128
139 + 480989 = 481128

Showing the first eight; more decompositions exist.
