Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503138, here are decompositions:

7 + 503131 = 503138
61 + 503077 = 503138
277 + 502861 = 503138
331 + 502807 = 503138
367 + 502771 = 503138
409 + 502729 = 503138
421 + 502717 = 503138
439 + 502699 = 503138

Showing the first eight; more decompositions exist.
