Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12902, here are decompositions:

3 + 12899 = 12902
13 + 12889 = 12902
61 + 12841 = 12902
73 + 12829 = 12902
79 + 12823 = 12902
103 + 12799 = 12902
139 + 12763 = 12902
163 + 12739 = 12902

Showing the first eight; more decompositions exist.
