Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518498, here are decompositions:

31 + 518467 = 518498
67 + 518431 = 518498
109 + 518389 = 518498
157 + 518341 = 518498
199 + 518299 = 518498
307 + 518191 = 518498
367 + 518131 = 518498
397 + 518101 = 518498

Showing the first eight; more decompositions exist.
