Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518004, here are decompositions:

5 + 517999 = 518004
13 + 517991 = 518004
23 + 517981 = 518004
37 + 517967 = 518004
73 + 517931 = 518004
103 + 517901 = 518004
127 + 517877 = 518004
131 + 517873 = 518004

Showing the first eight; more decompositions exist.
