Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84542, here are decompositions:

19 + 84523 = 84542
43 + 84499 = 84542
61 + 84481 = 84542
79 + 84463 = 84542
151 + 84391 = 84542
193 + 84349 = 84542
223 + 84319 = 84542
229 + 84313 = 84542

Showing the first eight; more decompositions exist.
