Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505574, here are decompositions:

37 + 505537 = 505574
61 + 505513 = 505574
73 + 505501 = 505574
127 + 505447 = 505574
163 + 505411 = 505574
337 + 505237 = 505574
373 + 505201 = 505574
457 + 505117 = 505574

Showing the first eight; more decompositions exist.
