Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2136, here are decompositions:

5 + 2131 = 2136
7 + 2129 = 2136
23 + 2113 = 2136
37 + 2099 = 2136
47 + 2089 = 2136
53 + 2083 = 2136
67 + 2069 = 2136
73 + 2063 = 2136

Showing the first eight; more decompositions exist.
