Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87464, here are decompositions:

31 + 87433 = 87464
37 + 87427 = 87464
43 + 87421 = 87464
61 + 87403 = 87464
127 + 87337 = 87464
151 + 87313 = 87464
211 + 87253 = 87464
241 + 87223 = 87464

Showing the first eight; more decompositions exist.
