Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529840, here are decompositions:

11 + 529829 = 529840
29 + 529811 = 529840
89 + 529751 = 529840
131 + 529709 = 529840
149 + 529691 = 529840
167 + 529673 = 529840
191 + 529649 = 529840
263 + 529577 = 529840

Showing the first eight; more decompositions exist.
