Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87276, here are decompositions:

19 + 87257 = 87276
23 + 87253 = 87276
53 + 87223 = 87276
89 + 87187 = 87276
97 + 87179 = 87276
127 + 87149 = 87276
157 + 87119 = 87276
173 + 87103 = 87276

Showing the first eight; more decompositions exist.
