Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154458, here are decompositions:

19 + 154439 = 154458
41 + 154417 = 154458
71 + 154387 = 154458
89 + 154369 = 154458
107 + 154351 = 154458
137 + 154321 = 154458
167 + 154291 = 154458
179 + 154279 = 154458

Showing the first eight; more decompositions exist.
