Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158748, here are decompositions:

17 + 158731 = 158748
101 + 158647 = 158748
127 + 158621 = 158748
131 + 158617 = 158748
137 + 158611 = 158748
151 + 158597 = 158748
157 + 158591 = 158748
167 + 158581 = 158748

Showing the first eight; more decompositions exist.
