Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505928, here are decompositions:

61 + 505867 = 505928
109 + 505819 = 505928
151 + 505777 = 505928
271 + 505657 = 505928
499 + 505429 = 505928
571 + 505357 = 505928
601 + 505327 = 505928
607 + 505321 = 505928

Showing the first eight; more decompositions exist.
