Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492542, here are decompositions:

19 + 492523 = 492542
31 + 492511 = 492542
79 + 492463 = 492542
139 + 492403 = 492542
223 + 492319 = 492542
439 + 492103 = 492542
619 + 491923 = 492542
643 + 491899 = 492542

Showing the first eight; more decompositions exist.
