Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87466, here are decompositions:

23 + 87443 = 87466
59 + 87407 = 87466
83 + 87383 = 87466
107 + 87359 = 87466
149 + 87317 = 87466
167 + 87299 = 87466
173 + 87293 = 87466
317 + 87149 = 87466

Showing the first eight; more decompositions exist.
