Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518446, here are decompositions:

17 + 518429 = 518446
29 + 518417 = 518446
59 + 518387 = 518446
197 + 518249 = 518446
239 + 518207 = 518446
293 + 518153 = 518446
317 + 518129 = 518446
347 + 518099 = 518446

Showing the first eight; more decompositions exist.
