Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87254, here are decompositions:

3 + 87251 = 87254
31 + 87223 = 87254
43 + 87211 = 87254
67 + 87187 = 87254
73 + 87181 = 87254
103 + 87151 = 87254
151 + 87103 = 87254
241 + 87013 = 87254

Showing the first eight; more decompositions exist.
