Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572128, here are decompositions:

41 + 572087 = 572128
59 + 572069 = 572128
101 + 572027 = 572128
251 + 571877 = 572128
257 + 571871 = 572128
281 + 571847 = 572128
317 + 571811 = 572128
419 + 571709 = 572128

Showing the first eight; more decompositions exist.
