Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2148, here are decompositions:

5 + 2143 = 2148
7 + 2141 = 2148
11 + 2137 = 2148
17 + 2131 = 2148
19 + 2129 = 2148
37 + 2111 = 2148
59 + 2089 = 2148
61 + 2087 = 2148

Showing the first eight; more decompositions exist.
