Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505782, here are decompositions:

5 + 505777 = 505782
19 + 505763 = 505782
23 + 505759 = 505782
71 + 505711 = 505782
73 + 505709 = 505782
89 + 505693 = 505782
113 + 505669 = 505782
139 + 505643 = 505782

Showing the first eight; more decompositions exist.
