Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104542, here are decompositions:

5 + 104537 = 104542
29 + 104513 = 104542
71 + 104471 = 104542
83 + 104459 = 104542
149 + 104393 = 104542
173 + 104369 = 104542
233 + 104309 = 104542
311 + 104231 = 104542

Showing the first eight; more decompositions exist.
