Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571542, here are decompositions:

11 + 571531 = 571542
71 + 571471 = 571542
89 + 571453 = 571542
109 + 571433 = 571542
173 + 571369 = 571542
211 + 571331 = 571542
239 + 571303 = 571542
263 + 571279 = 571542

Showing the first eight; more decompositions exist.
