Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81452, here are decompositions:

13 + 81439 = 81452
31 + 81421 = 81452
43 + 81409 = 81452
79 + 81373 = 81452
103 + 81349 = 81452
109 + 81343 = 81452
229 + 81223 = 81452
271 + 81181 = 81452

Showing the first eight; more decompositions exist.
