Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505946, here are decompositions:

19 + 505927 = 505946
79 + 505867 = 505946
127 + 505819 = 505946
277 + 505669 = 505946
283 + 505663 = 505946
307 + 505639 = 505946
313 + 505633 = 505946
373 + 505573 = 505946

Showing the first eight; more decompositions exist.
