Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87550, here are decompositions:

3 + 87547 = 87550
11 + 87539 = 87550
41 + 87509 = 87550
59 + 87491 = 87550
107 + 87443 = 87550
167 + 87383 = 87550
191 + 87359 = 87550
227 + 87323 = 87550

Showing the first eight; more decompositions exist.
