Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040542, here are decompositions:

11 + 1040531 = 1040542
53 + 1040489 = 1040542
59 + 1040483 = 1040542
131 + 1040411 = 1040542
353 + 1040189 = 1040542
359 + 1040183 = 1040542
383 + 1040159 = 1040542
389 + 1040153 = 1040542

Showing the first eight; more decompositions exist.
