Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 504728, here are decompositions:

61 + 504667 = 504728
67 + 504661 = 504728
97 + 504631 = 504728
109 + 504619 = 504728
181 + 504547 = 504728
271 + 504457 = 504728
349 + 504379 = 504728
379 + 504349 = 504728

Showing the first eight; more decompositions exist.
