Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13050, here are decompositions:

7 + 13043 = 13050
13 + 13037 = 13050
17 + 13033 = 13050
41 + 13009 = 13050
43 + 13007 = 13050
47 + 13003 = 13050
67 + 12983 = 13050
71 + 12979 = 13050

Showing the first eight; more decompositions exist.
