Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515246, here are decompositions:

13 + 515233 = 515246
19 + 515227 = 515246
73 + 515173 = 515246
97 + 515149 = 515246
103 + 515143 = 515246
157 + 515089 = 515246
307 + 514939 = 515246
313 + 514933 = 515246

Showing the first eight; more decompositions exist.
