Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503686, here are decompositions:

23 + 503663 = 503686
137 + 503549 = 503686
233 + 503453 = 503686
263 + 503423 = 503686
317 + 503369 = 503686
347 + 503339 = 503686
383 + 503303 = 503686
389 + 503297 = 503686

Showing the first eight; more decompositions exist.
