Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503172, here are decompositions:

13 + 503159 = 503172
41 + 503131 = 503172
199 + 502973 = 503172
211 + 502961 = 503172
251 + 502921 = 503172
311 + 502861 = 503172
331 + 502841 = 503172
353 + 502819 = 503172

Showing the first eight; more decompositions exist.
