Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481816, here are decompositions:

3 + 481813 = 481816
29 + 481787 = 481816
47 + 481769 = 481816
149 + 481667 = 481816
197 + 481619 = 481816
227 + 481589 = 481816
239 + 481577 = 481816
347 + 481469 = 481816

Showing the first eight; more decompositions exist.
