Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503518, here are decompositions:

17 + 503501 = 503518
137 + 503381 = 503518
149 + 503369 = 503518
167 + 503351 = 503518
179 + 503339 = 503518
251 + 503267 = 503518
269 + 503249 = 503518
311 + 503207 = 503518

Showing the first eight; more decompositions exist.
