Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505560, here are decompositions:

23 + 505537 = 505560
37 + 505523 = 505560
47 + 505513 = 505560
59 + 505501 = 505560
67 + 505493 = 505560
79 + 505481 = 505560
101 + 505459 = 505560
113 + 505447 = 505560

Showing the first eight; more decompositions exist.
