Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87736, here are decompositions:

17 + 87719 = 87736
53 + 87683 = 87736
107 + 87629 = 87736
113 + 87623 = 87736
149 + 87587 = 87736
179 + 87557 = 87736
197 + 87539 = 87736
227 + 87509 = 87736

Showing the first eight; more decompositions exist.
