Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529378, here are decompositions:

29 + 529349 = 529378
71 + 529307 = 529378
107 + 529271 = 529378
137 + 529241 = 529378
149 + 529229 = 529378
197 + 529181 = 529378
251 + 529127 = 529378
257 + 529121 = 529378

Showing the first eight; more decompositions exist.
