Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024542, here are decompositions:

19 + 1024523 = 1024542
31 + 1024511 = 1024542
61 + 1024481 = 1024542
109 + 1024433 = 1024542
131 + 1024411 = 1024542
151 + 1024391 = 1024542
163 + 1024379 = 1024542
223 + 1024319 = 1024542

Showing the first eight; more decompositions exist.
