Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154152, here are decompositions:

41 + 154111 = 154152
71 + 154081 = 154152
73 + 154079 = 154152
79 + 154073 = 154152
109 + 154043 = 154152
151 + 154001 = 154152
199 + 153953 = 154152
211 + 153941 = 154152

Showing the first eight; more decompositions exist.
