Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493542, here are decompositions:

11 + 493531 = 493542
19 + 493523 = 493542
61 + 493481 = 493542
79 + 493463 = 493542
109 + 493433 = 493542
139 + 493403 = 493542
149 + 493393 = 493542
173 + 493369 = 493542

Showing the first eight; more decompositions exist.
