Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503428, here are decompositions:

5 + 503423 = 503428
47 + 503381 = 503428
59 + 503369 = 503428
89 + 503339 = 503428
131 + 503297 = 503428
179 + 503249 = 503428
197 + 503231 = 503428
269 + 503159 = 503428

Showing the first eight; more decompositions exist.
