Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515982, here are decompositions:

13 + 515969 = 515982
31 + 515951 = 515982
41 + 515941 = 515982
53 + 515929 = 515982
59 + 515923 = 515982
109 + 515873 = 515982
139 + 515843 = 515982
179 + 515803 = 515982

Showing the first eight; more decompositions exist.
