Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87274, here are decompositions:

17 + 87257 = 87274
23 + 87251 = 87274
53 + 87221 = 87274
167 + 87107 = 87274
191 + 87083 = 87274
233 + 87041 = 87274
263 + 87011 = 87274
281 + 86993 = 87274

Showing the first eight; more decompositions exist.
