Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518224, here are decompositions:

17 + 518207 = 518224
53 + 518171 = 518224
71 + 518153 = 518224
101 + 518123 = 518224
167 + 518057 = 518224
233 + 517991 = 518224
257 + 517967 = 518224
293 + 517931 = 518224

Showing the first eight; more decompositions exist.
