Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505764, here are decompositions:

5 + 505759 = 505764
37 + 505727 = 505764
53 + 505711 = 505764
71 + 505693 = 505764
73 + 505691 = 505764
101 + 505663 = 505764
107 + 505657 = 505764
131 + 505633 = 505764

Showing the first eight; more decompositions exist.
