Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21114, here are decompositions:

7 + 21107 = 21114
13 + 21101 = 21114
47 + 21067 = 21114
53 + 21061 = 21114
83 + 21031 = 21114
97 + 21017 = 21114
101 + 21013 = 21114
103 + 21011 = 21114

Showing the first eight; more decompositions exist.
