Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15926, here are decompositions:

3 + 15923 = 15926
7 + 15919 = 15926
13 + 15913 = 15926
19 + 15907 = 15926
37 + 15889 = 15926
67 + 15859 = 15926
103 + 15823 = 15926
109 + 15817 = 15926

Showing the first eight; more decompositions exist.
