Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503578, here are decompositions:

29 + 503549 = 503578
137 + 503441 = 503578
197 + 503381 = 503578
227 + 503351 = 503578
239 + 503339 = 503578
281 + 503297 = 503578
311 + 503267 = 503578
347 + 503231 = 503578

Showing the first eight; more decompositions exist.
