Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512572, here are decompositions:

3 + 512569 = 512572
29 + 512543 = 512572
41 + 512531 = 512572
239 + 512333 = 512572
251 + 512321 = 512572
479 + 512093 = 512572
563 + 512009 = 512572
761 + 511811 = 512572

Showing the first eight; more decompositions exist.
