Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85402, here are decompositions:

41 + 85361 = 85402
71 + 85331 = 85402
89 + 85313 = 85402
173 + 85229 = 85402
179 + 85223 = 85402
269 + 85133 = 85402
281 + 85121 = 85402
293 + 85109 = 85402

Showing the first eight; more decompositions exist.
