Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51810, here are decompositions:

7 + 51803 = 51810
13 + 51797 = 51810
23 + 51787 = 51810
41 + 51769 = 51810
43 + 51767 = 51810
61 + 51749 = 51810
89 + 51721 = 51810
97 + 51713 = 51810

Showing the first eight; more decompositions exist.
