Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87804, here are decompositions:

7 + 87797 = 87804
11 + 87793 = 87804
37 + 87767 = 87804
53 + 87751 = 87804
61 + 87743 = 87804
83 + 87721 = 87804
103 + 87701 = 87804
107 + 87697 = 87804

Showing the first eight; more decompositions exist.
