Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481256, here are decompositions:

7 + 481249 = 481256
79 + 481177 = 481256
103 + 481153 = 481256
109 + 481147 = 481256
163 + 481093 = 481256
277 + 480979 = 481256
337 + 480919 = 481256
673 + 480583 = 481256

Showing the first eight; more decompositions exist.
