Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15798, here are decompositions:

7 + 15791 = 15798
11 + 15787 = 15798
31 + 15767 = 15798
37 + 15761 = 15798
59 + 15739 = 15798
61 + 15737 = 15798
67 + 15731 = 15798
71 + 15727 = 15798

Showing the first eight; more decompositions exist.
