Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87556, here are decompositions:

3 + 87553 = 87556
17 + 87539 = 87556
47 + 87509 = 87556
83 + 87473 = 87556
113 + 87443 = 87556
149 + 87407 = 87556
173 + 87383 = 87556
197 + 87359 = 87556

Showing the first eight; more decompositions exist.
