Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85428, here are decompositions:

17 + 85411 = 85428
47 + 85381 = 85428
59 + 85369 = 85428
67 + 85361 = 85428
97 + 85331 = 85428
131 + 85297 = 85428
181 + 85247 = 85428
191 + 85237 = 85428

Showing the first eight; more decompositions exist.
