Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529420, here are decompositions:

71 + 529349 = 529420
107 + 529313 = 529420
113 + 529307 = 529420
149 + 529271 = 529420
179 + 529241 = 529420
191 + 529229 = 529420
239 + 529181 = 529420
263 + 529157 = 529420

Showing the first eight; more decompositions exist.
