Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11802, here are decompositions:

13 + 11789 = 11802
19 + 11783 = 11802
23 + 11779 = 11802
59 + 11743 = 11802
71 + 11731 = 11802
83 + 11719 = 11802
101 + 11701 = 11802
103 + 11699 = 11802

Showing the first eight; more decompositions exist.
