Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154542, here are decompositions:

19 + 154523 = 154542
41 + 154501 = 154542
83 + 154459 = 154542
103 + 154439 = 154542
173 + 154369 = 154542
191 + 154351 = 154542
229 + 154313 = 154542
239 + 154303 = 154542

Showing the first eight; more decompositions exist.
