Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518272, here are decompositions:

11 + 518261 = 518272
23 + 518249 = 518272
101 + 518171 = 518272
113 + 518159 = 518272
149 + 518123 = 518272
173 + 518099 = 518272
281 + 517991 = 518272
353 + 517919 = 518272

Showing the first eight; more decompositions exist.
