Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572572, here are decompositions:

5 + 572567 = 572572
23 + 572549 = 572572
53 + 572519 = 572572
101 + 572471 = 572572
149 + 572423 = 572572
173 + 572399 = 572572
239 + 572333 = 572572
251 + 572321 = 572572

Showing the first eight; more decompositions exist.
