Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042542, here are decompositions:

13 + 1042529 = 1042542
19 + 1042523 = 1042542
23 + 1042519 = 1042542
73 + 1042469 = 1042542
103 + 1042439 = 1042542
173 + 1042369 = 1042542
211 + 1042331 = 1042542
233 + 1042309 = 1042542

Showing the first eight; more decompositions exist.
