Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154494, here are decompositions:

7 + 154487 = 154494
71 + 154423 = 154494
107 + 154387 = 154494
173 + 154321 = 154494
181 + 154313 = 154494
191 + 154303 = 154494
227 + 154267 = 154494
251 + 154243 = 154494

Showing the first eight; more decompositions exist.
