Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503018, here are decompositions:

97 + 502921 = 503018
157 + 502861 = 503018
199 + 502819 = 503018
211 + 502807 = 503018
331 + 502687 = 503018
349 + 502669 = 503018
367 + 502651 = 503018
421 + 502597 = 503018

Showing the first eight; more decompositions exist.
