Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158220, here are decompositions:

11 + 158209 = 158220
19 + 158201 = 158220
31 + 158189 = 158220
59 + 158161 = 158220
79 + 158141 = 158220
107 + 158113 = 158220
149 + 158071 = 158220
173 + 158047 = 158220

Showing the first eight; more decompositions exist.
