Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503198, here are decompositions:

61 + 503137 = 503198
67 + 503131 = 503198
181 + 503017 = 503198
277 + 502921 = 503198
337 + 502861 = 503198
379 + 502819 = 503198
499 + 502699 = 503198
547 + 502651 = 503198

Showing the first eight; more decompositions exist.
