Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505968, here are decompositions:

7 + 505961 = 505968
19 + 505949 = 505968
41 + 505927 = 505968
61 + 505907 = 505968
97 + 505871 = 505968
101 + 505867 = 505968
149 + 505819 = 505968
157 + 505811 = 505968

Showing the first eight; more decompositions exist.
