Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39802, here are decompositions:

3 + 39799 = 39802
11 + 39791 = 39802
23 + 39779 = 39802
41 + 39761 = 39802
53 + 39749 = 39802
83 + 39719 = 39802
131 + 39671 = 39802
179 + 39623 = 39802

Showing the first eight; more decompositions exist.
