Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500728, here are decompositions:

5 + 500723 = 500728
29 + 500699 = 500728
149 + 500579 = 500728
227 + 500501 = 500728
257 + 500471 = 500728
269 + 500459 = 500728
311 + 500417 = 500728
359 + 500369 = 500728

Showing the first eight; more decompositions exist.
