Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85452, here are decompositions:

5 + 85447 = 85452
13 + 85439 = 85452
23 + 85429 = 85452
41 + 85411 = 85452
71 + 85381 = 85452
83 + 85369 = 85452
89 + 85363 = 85452
139 + 85313 = 85452

Showing the first eight; more decompositions exist.
