Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85372, here are decompositions:

3 + 85369 = 85372
11 + 85361 = 85372
41 + 85331 = 85372
59 + 85313 = 85372
113 + 85259 = 85372
149 + 85223 = 85372
173 + 85199 = 85372
179 + 85193 = 85372

Showing the first eight; more decompositions exist.
