Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155202, here are decompositions:

11 + 155191 = 155202
31 + 155171 = 155202
41 + 155161 = 155202
83 + 155119 = 155202
193 + 155009 = 155202
199 + 155003 = 155202
211 + 154991 = 155202
269 + 154933 = 155202

Showing the first eight; more decompositions exist.
