Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481810, here are decompositions:

3 + 481807 = 481810
23 + 481787 = 481810
41 + 481769 = 481810
59 + 481751 = 481810
89 + 481721 = 481810
113 + 481697 = 481810
137 + 481673 = 481810
191 + 481619 = 481810

Showing the first eight; more decompositions exist.
