Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87452, here are decompositions:

19 + 87433 = 87452
31 + 87421 = 87452
139 + 87313 = 87452
199 + 87253 = 87452
229 + 87223 = 87452
241 + 87211 = 87452
271 + 87181 = 87452
331 + 87121 = 87452

Showing the first eight; more decompositions exist.
