Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12992, here are decompositions:

13 + 12979 = 12992
19 + 12973 = 12992
73 + 12919 = 12992
103 + 12889 = 12992
139 + 12853 = 12992
151 + 12841 = 12992
163 + 12829 = 12992
193 + 12799 = 12992

Showing the first eight; more decompositions exist.
