Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529750, here are decompositions:

3 + 529747 = 529750
41 + 529709 = 529750
59 + 529691 = 529750
101 + 529649 = 529750
113 + 529637 = 529750
131 + 529619 = 529750
173 + 529577 = 529750
233 + 529517 = 529750

Showing the first eight; more decompositions exist.
