Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501544, here are decompositions:

41 + 501503 = 501544
227 + 501317 = 501544
257 + 501287 = 501544
311 + 501233 = 501544
347 + 501197 = 501544
353 + 501191 = 501544
467 + 501077 = 501544
587 + 500957 = 501544

Showing the first eight; more decompositions exist.
