Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87904, here are decompositions:

17 + 87887 = 87904
23 + 87881 = 87904
71 + 87833 = 87904
101 + 87803 = 87904
107 + 87797 = 87904
137 + 87767 = 87904
233 + 87671 = 87904
263 + 87641 = 87904

Showing the first eight; more decompositions exist.
