Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81632, here are decompositions:

3 + 81629 = 81632
13 + 81619 = 81632
73 + 81559 = 81632
79 + 81553 = 81632
193 + 81439 = 81632
211 + 81421 = 81632
223 + 81409 = 81632
283 + 81349 = 81632

Showing the first eight; more decompositions exist.
