Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505956, here are decompositions:

7 + 505949 = 505956
29 + 505927 = 505956
37 + 505919 = 505956
79 + 505877 = 505956
89 + 505867 = 505956
137 + 505819 = 505956
179 + 505777 = 505956
193 + 505763 = 505956

Showing the first eight; more decompositions exist.
