Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40810, here are decompositions:

23 + 40787 = 40810
47 + 40763 = 40810
59 + 40751 = 40810
71 + 40739 = 40810
101 + 40709 = 40810
113 + 40697 = 40810
173 + 40637 = 40810
227 + 40583 = 40810

Showing the first eight; more decompositions exist.
