Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572228, here are decompositions:

67 + 572161 = 572228
367 + 571861 = 572228
439 + 571789 = 572228
487 + 571741 = 572228
571 + 571657 = 572228
751 + 571477 = 572228
757 + 571471 = 572228
829 + 571399 = 572228

Showing the first eight; more decompositions exist.
