Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538542, here are decompositions:

13 + 538529 = 538542
19 + 538523 = 538542
23 + 538519 = 538542
29 + 538513 = 538542
31 + 538511 = 538542
61 + 538481 = 538542
71 + 538471 = 538542
131 + 538411 = 538542

Showing the first eight; more decompositions exist.
