Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130810, here are decompositions:

3 + 130807 = 130810
23 + 130787 = 130810
41 + 130769 = 130810
167 + 130643 = 130810
179 + 130631 = 130810
191 + 130619 = 130810
257 + 130553 = 130810
263 + 130547 = 130810

Showing the first eight; more decompositions exist.
