Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155058, here are decompositions:

11 + 155047 = 155058
31 + 155027 = 155058
41 + 155017 = 155058
67 + 154991 = 155058
131 + 154927 = 155058
181 + 154877 = 155058
251 + 154807 = 155058
269 + 154789 = 155058

Showing the first eight; more decompositions exist.
