Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572442, here are decompositions:

5 + 572437 = 572442
19 + 572423 = 572442
23 + 572419 = 572442
43 + 572399 = 572442
109 + 572333 = 572442
113 + 572329 = 572442
131 + 572311 = 572442
139 + 572303 = 572442

Showing the first eight; more decompositions exist.
