Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168542, here are decompositions:

19 + 168523 = 168542
43 + 168499 = 168542
61 + 168481 = 168542
79 + 168463 = 168542
109 + 168433 = 168542
151 + 168391 = 168542
211 + 168331 = 168542
331 + 168211 = 168542

Showing the first eight; more decompositions exist.
