Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515964, here are decompositions:

13 + 515951 = 515964
23 + 515941 = 515964
41 + 515923 = 515964
47 + 515917 = 515964
103 + 515861 = 515964
107 + 515857 = 515964
151 + 515813 = 515964
181 + 515783 = 515964

Showing the first eight; more decompositions exist.
