Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571508, here are decompositions:

31 + 571477 = 571508
37 + 571471 = 571508
109 + 571399 = 571508
127 + 571381 = 571508
139 + 571369 = 571508
229 + 571279 = 571508
241 + 571267 = 571508
277 + 571231 = 571508

Showing the first eight; more decompositions exist.
