Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65904, here are decompositions:

5 + 65899 = 65904
23 + 65881 = 65904
37 + 65867 = 65904
53 + 65851 = 65904
61 + 65843 = 65904
67 + 65837 = 65904
73 + 65831 = 65904
127 + 65777 = 65904

Showing the first eight; more decompositions exist.
