Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518254, here are decompositions:

5 + 518249 = 518254
17 + 518237 = 518254
47 + 518207 = 518254
83 + 518171 = 518254
101 + 518153 = 518254
131 + 518123 = 518254
197 + 518057 = 518254
263 + 517991 = 518254

Showing the first eight; more decompositions exist.
