Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20964, here are decompositions:

5 + 20959 = 20964
17 + 20947 = 20964
43 + 20921 = 20964
61 + 20903 = 20964
67 + 20897 = 20964
107 + 20857 = 20964
157 + 20807 = 20964
191 + 20773 = 20964

Showing the first eight; more decompositions exist.
