Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515966, here are decompositions:

37 + 515929 = 515966
43 + 515923 = 515966
79 + 515887 = 515966
109 + 515857 = 515966
127 + 515839 = 515966
163 + 515803 = 515966
193 + 515773 = 515966
229 + 515737 = 515966

Showing the first eight; more decompositions exist.
