Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154248, here are decompositions:

5 + 154243 = 154248
19 + 154229 = 154248
37 + 154211 = 154248
67 + 154181 = 154248
89 + 154159 = 154248
137 + 154111 = 154248
151 + 154097 = 154248
167 + 154081 = 154248

Showing the first eight; more decompositions exist.
