Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557542, here are decompositions:

5 + 557537 = 557542
23 + 557519 = 557542
53 + 557489 = 557542
59 + 557483 = 557542
173 + 557369 = 557542
233 + 557309 = 557542
239 + 557303 = 557542
269 + 557273 = 557542

Showing the first eight; more decompositions exist.
