Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503178, here are decompositions:

19 + 503159 = 503178
31 + 503147 = 503178
41 + 503137 = 503178
47 + 503131 = 503178
101 + 503077 = 503178
139 + 503039 = 503178
241 + 502937 = 503178
257 + 502921 = 503178

Showing the first eight; more decompositions exist.
