Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529972, here are decompositions:

11 + 529961 = 529972
101 + 529871 = 529972
263 + 529709 = 529972
281 + 529691 = 529972
353 + 529619 = 529972
659 + 529313 = 529972
701 + 529271 = 529972
743 + 529229 = 529972

Showing the first eight; more decompositions exist.
