Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65184, here are decompositions:

5 + 65179 = 65184
11 + 65173 = 65184
13 + 65171 = 65184
17 + 65167 = 65184
37 + 65147 = 65184
43 + 65141 = 65184
61 + 65123 = 65184
73 + 65111 = 65184

Showing the first eight; more decompositions exist.
