Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503540, here are decompositions:

109 + 503431 = 503540
127 + 503413 = 503540
151 + 503389 = 503540
157 + 503383 = 503540
181 + 503359 = 503540
223 + 503317 = 503540
307 + 503233 = 503540
313 + 503227 = 503540

Showing the first eight; more decompositions exist.
