Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139158, here are decompositions:

37 + 139121 = 139158
67 + 139091 = 139158
79 + 139079 = 139158
137 + 139021 = 139158
181 + 138977 = 139158
191 + 138967 = 139158
199 + 138959 = 139158
241 + 138917 = 139158

Showing the first eight; more decompositions exist.
