Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 461640, here are decompositions:

13 + 461627 = 461640
31 + 461609 = 461640
37 + 461603 = 461640
41 + 461599 = 461640
59 + 461581 = 461640
71 + 461569 = 461640
79 + 461561 = 461640
173 + 461467 = 461640

Showing the first eight; more decompositions exist.
