Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11100, here are decompositions:

7 + 11093 = 11100
13 + 11087 = 11100
17 + 11083 = 11100
29 + 11071 = 11100
31 + 11069 = 11100
41 + 11059 = 11100
43 + 11057 = 11100
53 + 11047 = 11100

Showing the first eight; more decompositions exist.
