Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518202, here are decompositions:

11 + 518191 = 518202
23 + 518179 = 518202
31 + 518171 = 518202
43 + 518159 = 518202
71 + 518131 = 518202
73 + 518129 = 518202
79 + 518123 = 518202
89 + 518113 = 518202

Showing the first eight; more decompositions exist.
