Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158814, here are decompositions:

11 + 158803 = 158814
23 + 158791 = 158814
37 + 158777 = 158814
43 + 158771 = 158814
53 + 158761 = 158814
67 + 158747 = 158814
83 + 158731 = 158814
151 + 158663 = 158814

Showing the first eight; more decompositions exist.
