Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505850, here are decompositions:

31 + 505819 = 505850
73 + 505777 = 505850
139 + 505711 = 505850
157 + 505693 = 505850
181 + 505669 = 505850
193 + 505657 = 505850
211 + 505639 = 505850
277 + 505573 = 505850

Showing the first eight; more decompositions exist.
