Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15814, here are decompositions:

5 + 15809 = 15814
11 + 15803 = 15814
17 + 15797 = 15814
23 + 15791 = 15814
41 + 15773 = 15814
47 + 15767 = 15814
53 + 15761 = 15814
83 + 15731 = 15814

Showing the first eight; more decompositions exist.
