Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938542, here are decompositions:

5 + 938537 = 938542
83 + 938459 = 938542
89 + 938453 = 938542
149 + 938393 = 938542
173 + 938369 = 938542
191 + 938351 = 938542
233 + 938309 = 938542
263 + 938279 = 938542

Showing the first eight; more decompositions exist.
