Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87766, here are decompositions:

23 + 87743 = 87766
47 + 87719 = 87766
83 + 87683 = 87766
137 + 87629 = 87766
179 + 87587 = 87766
227 + 87539 = 87766
257 + 87509 = 87766
293 + 87473 = 87766

Showing the first eight; more decompositions exist.
