Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154278, here are decompositions:

11 + 154267 = 154278
31 + 154247 = 154278
67 + 154211 = 154278
97 + 154181 = 154278
151 + 154127 = 154278
167 + 154111 = 154278
181 + 154097 = 154278
191 + 154087 = 154278

Showing the first eight; more decompositions exist.
