Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2102, here are decompositions:

3 + 2099 = 2102
13 + 2089 = 2102
19 + 2083 = 2102
73 + 2029 = 2102
103 + 1999 = 2102
109 + 1993 = 2102
151 + 1951 = 2102
223 + 1879 = 2102

Showing the first eight; more decompositions exist.
