Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571528, here are decompositions:

131 + 571397 = 571528
197 + 571331 = 571528
317 + 571211 = 571528
479 + 571049 = 571528
491 + 571037 = 571528
509 + 571019 = 571528
569 + 570959 = 571528
641 + 570887 = 571528

Showing the first eight; more decompositions exist.
