Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572540, here are decompositions:

19 + 572521 = 572540
43 + 572497 = 572540
61 + 572479 = 572540
79 + 572461 = 572540
103 + 572437 = 572540
211 + 572329 = 572540
229 + 572311 = 572540
271 + 572269 = 572540

Showing the first eight; more decompositions exist.
