Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2154, here are decompositions:

11 + 2143 = 2154
13 + 2141 = 2154
17 + 2137 = 2154
23 + 2131 = 2154
41 + 2113 = 2154
43 + 2111 = 2154
67 + 2087 = 2154
71 + 2083 = 2154

Showing the first eight; more decompositions exist.
