Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158690, here are decompositions:

43 + 158647 = 158690
73 + 158617 = 158690
79 + 158611 = 158690
109 + 158581 = 158690
127 + 158563 = 158690
139 + 158551 = 158690
163 + 158527 = 158690
241 + 158449 = 158690

Showing the first eight; more decompositions exist.
