Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529438, here are decompositions:

17 + 529421 = 529438
89 + 529349 = 529438
131 + 529307 = 529438
137 + 529301 = 529438
167 + 529271 = 529438
179 + 529259 = 529438
197 + 529241 = 529438
257 + 529181 = 529438

Showing the first eight; more decompositions exist.
