Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15930, here are decompositions:

7 + 15923 = 15930
11 + 15919 = 15930
17 + 15913 = 15930
23 + 15907 = 15930
29 + 15901 = 15930
41 + 15889 = 15930
43 + 15887 = 15930
53 + 15877 = 15930

Showing the first eight; more decompositions exist.
