Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515552, here are decompositions:

13 + 515539 = 515552
151 + 515401 = 515552
181 + 515371 = 515552
229 + 515323 = 515552
241 + 515311 = 515552
379 + 515173 = 515552
409 + 515143 = 515552
463 + 515089 = 515552

Showing the first eight; more decompositions exist.
