Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158810, here are decompositions:

7 + 158803 = 158810
19 + 158791 = 158810
61 + 158749 = 158810
79 + 158731 = 158810
163 + 158647 = 158810
193 + 158617 = 158810
199 + 158611 = 158810
229 + 158581 = 158810

Showing the first eight; more decompositions exist.
