Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515936, here are decompositions:

7 + 515929 = 515936
13 + 515923 = 515936
19 + 515917 = 515936
79 + 515857 = 515936
97 + 515839 = 515936
163 + 515773 = 515936
199 + 515737 = 515936
283 + 515653 = 515936

Showing the first eight; more decompositions exist.
