Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17930, here are decompositions:

7 + 17923 = 17930
19 + 17911 = 17930
67 + 17863 = 17930
79 + 17851 = 17930
103 + 17827 = 17930
139 + 17791 = 17930
181 + 17749 = 17930
193 + 17737 = 17930

Showing the first eight; more decompositions exist.
