Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81532, here are decompositions:

5 + 81527 = 81532
23 + 81509 = 81532
131 + 81401 = 81532
173 + 81359 = 81532
179 + 81353 = 81532
233 + 81299 = 81532
239 + 81293 = 81532
251 + 81281 = 81532

Showing the first eight; more decompositions exist.
