Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17964, here are decompositions:

5 + 17959 = 17964
7 + 17957 = 17964
41 + 17923 = 17964
43 + 17921 = 17964
53 + 17911 = 17964
61 + 17903 = 17964
73 + 17891 = 17964
83 + 17881 = 17964

Showing the first eight; more decompositions exist.
