Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87526, here are decompositions:

3 + 87523 = 87526
17 + 87509 = 87526
53 + 87473 = 87526
83 + 87443 = 87526
167 + 87359 = 87526
227 + 87299 = 87526
233 + 87293 = 87526
269 + 87257 = 87526

Showing the first eight; more decompositions exist.
