Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503506, here are decompositions:

5 + 503501 = 503506
23 + 503483 = 503506
53 + 503453 = 503506
83 + 503423 = 503506
137 + 503369 = 503506
167 + 503339 = 503506
239 + 503267 = 503506
257 + 503249 = 503506

Showing the first eight; more decompositions exist.
