Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572440, here are decompositions:

3 + 572437 = 572440
17 + 572423 = 572440
23 + 572417 = 572440
41 + 572399 = 572440
53 + 572387 = 572440
83 + 572357 = 572440
107 + 572333 = 572440
137 + 572303 = 572440

Showing the first eight; more decompositions exist.
