Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513212, here are decompositions:

43 + 513169 = 513212
103 + 513109 = 513212
109 + 513103 = 513212
181 + 513031 = 513212
199 + 513013 = 513212
211 + 513001 = 513212
223 + 512989 = 513212
283 + 512929 = 513212

Showing the first eight; more decompositions exist.
