Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179810, here are decompositions:

3 + 179807 = 179810
31 + 179779 = 179810
61 + 179749 = 179810
67 + 179743 = 179810
73 + 179737 = 179810
139 + 179671 = 179810
151 + 179659 = 179810
229 + 179581 = 179810

Showing the first eight; more decompositions exist.
