Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87726, here are decompositions:

5 + 87721 = 87726
7 + 87719 = 87726
29 + 87697 = 87726
43 + 87683 = 87726
47 + 87679 = 87726
83 + 87643 = 87726
97 + 87629 = 87726
103 + 87623 = 87726

Showing the first eight; more decompositions exist.
