Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27802, here are decompositions:

3 + 27799 = 27802
11 + 27791 = 27802
23 + 27779 = 27802
29 + 27773 = 27802
53 + 27749 = 27802
59 + 27743 = 27802
101 + 27701 = 27802
113 + 27689 = 27802

Showing the first eight; more decompositions exist.
