Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518404, here are decompositions:

17 + 518387 = 518404
113 + 518291 = 518404
167 + 518237 = 518404
197 + 518207 = 518404
233 + 518171 = 518404
251 + 518153 = 518404
281 + 518123 = 518404
347 + 518057 = 518404

Showing the first eight; more decompositions exist.
