Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518008, here are decompositions:

17 + 517991 = 518008
41 + 517967 = 518008
59 + 517949 = 518008
89 + 517919 = 518008
107 + 517901 = 518008
131 + 517877 = 518008
191 + 517817 = 518008
269 + 517739 = 518008

Showing the first eight; more decompositions exist.
