Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508538, here are decompositions:

7 + 508531 = 508538
61 + 508477 = 508538
67 + 508471 = 508538
211 + 508327 = 508538
241 + 508297 = 508538
367 + 508171 = 508538
379 + 508159 = 508538
409 + 508129 = 508538

Showing the first eight; more decompositions exist.
