Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12802, here are decompositions:

3 + 12799 = 12802
11 + 12791 = 12802
59 + 12743 = 12802
89 + 12713 = 12802
113 + 12689 = 12802
131 + 12671 = 12802
149 + 12653 = 12802
191 + 12611 = 12802

Showing the first eight; more decompositions exist.
