Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11130, here are decompositions:

11 + 11119 = 11130
13 + 11117 = 11130
17 + 11113 = 11130
37 + 11093 = 11130
43 + 11087 = 11130
47 + 11083 = 11130
59 + 11071 = 11130
61 + 11069 = 11130

Showing the first eight; more decompositions exist.
