Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87284, here are decompositions:

3 + 87281 = 87284
7 + 87277 = 87284
31 + 87253 = 87284
61 + 87223 = 87284
73 + 87211 = 87284
97 + 87187 = 87284
103 + 87181 = 87284
151 + 87133 = 87284

Showing the first eight; more decompositions exist.
