Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503128, here are decompositions:

5 + 503123 = 503128
89 + 503039 = 503128
167 + 502961 = 503128
191 + 502937 = 503128
281 + 502847 = 503128
347 + 502781 = 503128
359 + 502769 = 503128
641 + 502487 = 503128

Showing the first eight; more decompositions exist.
