Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993664, here are decompositions:

17 + 993647 = 993664
47 + 993617 = 993664
53 + 993611 = 993664
107 + 993557 = 993664
137 + 993527 = 993664
197 + 993467 = 993664
227 + 993437 = 993664
233 + 993431 = 993664

Showing the first eight; more decompositions exist.
