Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87532, here are decompositions:

23 + 87509 = 87532
41 + 87491 = 87532
59 + 87473 = 87532
89 + 87443 = 87532
149 + 87383 = 87532
173 + 87359 = 87532
233 + 87299 = 87532
239 + 87293 = 87532

Showing the first eight; more decompositions exist.
