Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184542, here are decompositions:

19 + 184523 = 184542
31 + 184511 = 184542
53 + 184489 = 184542
79 + 184463 = 184542
101 + 184441 = 184542
173 + 184369 = 184542
191 + 184351 = 184542
233 + 184309 = 184542

Showing the first eight; more decompositions exist.
