Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109810, here are decompositions:

3 + 109807 = 109810
17 + 109793 = 109810
59 + 109751 = 109810
89 + 109721 = 109810
137 + 109673 = 109810
149 + 109661 = 109810
191 + 109619 = 109810
227 + 109583 = 109810

Showing the first eight; more decompositions exist.
