Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518416, here are decompositions:

5 + 518411 = 518416
29 + 518387 = 518416
89 + 518327 = 518416
167 + 518249 = 518416
179 + 518237 = 518416
257 + 518159 = 518416
263 + 518153 = 518416
293 + 518123 = 518416

Showing the first eight; more decompositions exist.
