Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529942, here are decompositions:

3 + 529939 = 529942
71 + 529871 = 529942
113 + 529829 = 529942
131 + 529811 = 529942
191 + 529751 = 529942
233 + 529709 = 529942
251 + 529691 = 529942
269 + 529673 = 529942

Showing the first eight; more decompositions exist.
