Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518212, here are decompositions:

3 + 518209 = 518212
5 + 518207 = 518212
41 + 518171 = 518212
53 + 518159 = 518212
59 + 518153 = 518212
83 + 518129 = 518212
89 + 518123 = 518212
113 + 518099 = 518212

Showing the first eight; more decompositions exist.
