Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572428, here are decompositions:

5 + 572423 = 572428
11 + 572417 = 572428
29 + 572399 = 572428
41 + 572387 = 572428
71 + 572357 = 572428
107 + 572321 = 572428
251 + 572177 = 572428
359 + 572069 = 572428

Showing the first eight; more decompositions exist.
