Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158450, here are decompositions:

7 + 158443 = 158450
31 + 158419 = 158450
43 + 158407 = 158450
79 + 158371 = 158450
109 + 158341 = 158450
157 + 158293 = 158450
181 + 158269 = 158450
223 + 158227 = 158450

Showing the first eight; more decompositions exist.
