Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515954, here are decompositions:

3 + 515951 = 515954
13 + 515941 = 515954
31 + 515923 = 515954
37 + 515917 = 515954
67 + 515887 = 515954
97 + 515857 = 515954
151 + 515803 = 515954
181 + 515773 = 515954

Showing the first eight; more decompositions exist.
