Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 535212, here are decompositions:

5 + 535207 = 535212
19 + 535193 = 535212
31 + 535181 = 535212
43 + 535169 = 535212
53 + 535159 = 535212
61 + 535151 = 535212
79 + 535133 = 535212
89 + 535123 = 535212

Showing the first eight; more decompositions exist.
