Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505752, here are decompositions:

41 + 505711 = 505752
43 + 505709 = 505752
59 + 505693 = 505752
61 + 505691 = 505752
83 + 505669 = 505752
89 + 505663 = 505752
109 + 505643 = 505752
113 + 505639 = 505752

Showing the first eight; more decompositions exist.
