Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503620, here are decompositions:

11 + 503609 = 503620
71 + 503549 = 503620
137 + 503483 = 503620
167 + 503453 = 503620
179 + 503441 = 503620
197 + 503423 = 503620
239 + 503381 = 503620
251 + 503369 = 503620

Showing the first eight; more decompositions exist.
