Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18056, here are decompositions:

7 + 18049 = 18056
13 + 18043 = 18056
43 + 18013 = 18056
67 + 17989 = 18056
79 + 17977 = 18056
97 + 17959 = 18056
127 + 17929 = 18056
193 + 17863 = 18056

Showing the first eight; more decompositions exist.
