Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505994, here are decompositions:

67 + 505927 = 505994
127 + 505867 = 505994
283 + 505711 = 505994
331 + 505663 = 505994
337 + 505657 = 505994
421 + 505573 = 505994
457 + 505537 = 505994
547 + 505447 = 505994

Showing the first eight; more decompositions exist.
