Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503188, here are decompositions:

29 + 503159 = 503188
41 + 503147 = 503188
149 + 503039 = 503188
227 + 502961 = 503188
251 + 502937 = 503188
269 + 502919 = 503188
347 + 502841 = 503188
359 + 502829 = 503188

Showing the first eight; more decompositions exist.
