Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17810, here are decompositions:

3 + 17807 = 17810
19 + 17791 = 17810
61 + 17749 = 17810
73 + 17737 = 17810
97 + 17713 = 17810
103 + 17707 = 17810
127 + 17683 = 17810
151 + 17659 = 17810

Showing the first eight; more decompositions exist.
