Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190158, here are decompositions:

11 + 190147 = 190158
29 + 190129 = 190158
37 + 190121 = 190158
61 + 190097 = 190158
107 + 190051 = 190158
127 + 190031 = 190158
131 + 190027 = 190158
181 + 189977 = 190158

Showing the first eight; more decompositions exist.
