Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10802, here are decompositions:

3 + 10799 = 10802
13 + 10789 = 10802
31 + 10771 = 10802
73 + 10729 = 10802
79 + 10723 = 10802
139 + 10663 = 10802
151 + 10651 = 10802
163 + 10639 = 10802

Showing the first eight; more decompositions exist.
