Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86158, here are decompositions:

41 + 86117 = 86158
47 + 86111 = 86158
89 + 86069 = 86158
131 + 86027 = 86158
167 + 85991 = 86158
227 + 85931 = 86158
269 + 85889 = 86158
311 + 85847 = 86158

Showing the first eight; more decompositions exist.
