Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154574, here are decompositions:

3 + 154571 = 154574
31 + 154543 = 154574
73 + 154501 = 154574
151 + 154423 = 154574
157 + 154417 = 154574
223 + 154351 = 154574
241 + 154333 = 154574
271 + 154303 = 154574

Showing the first eight; more decompositions exist.
