Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505874, here are decompositions:

3 + 505871 = 505874
7 + 505867 = 505874
97 + 505777 = 505874
163 + 505711 = 505874
181 + 505693 = 505874
211 + 505663 = 505874
241 + 505633 = 505874
337 + 505537 = 505874

Showing the first eight; more decompositions exist.
