Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505766, here are decompositions:

3 + 505763 = 505766
7 + 505759 = 505766
73 + 505693 = 505766
97 + 505669 = 505766
103 + 505663 = 505766
109 + 505657 = 505766
127 + 505639 = 505766
193 + 505573 = 505766

Showing the first eight; more decompositions exist.
