Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85212, here are decompositions:

11 + 85201 = 85212
13 + 85199 = 85212
19 + 85193 = 85212
53 + 85159 = 85212
79 + 85133 = 85212
103 + 85109 = 85212
109 + 85103 = 85212
131 + 85081 = 85212

Showing the first eight; more decompositions exist.
