Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519542, here are decompositions:

3 + 519539 = 519542
19 + 519523 = 519542
43 + 519499 = 519542
109 + 519433 = 519542
151 + 519391 = 519542
193 + 519349 = 519542
241 + 519301 = 519542
313 + 519229 = 519542

Showing the first eight; more decompositions exist.
