Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87458, here are decompositions:

31 + 87427 = 87458
37 + 87421 = 87458
181 + 87277 = 87458
271 + 87187 = 87458
277 + 87181 = 87458
307 + 87151 = 87458
337 + 87121 = 87458
409 + 87049 = 87458

Showing the first eight; more decompositions exist.
