Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105664, here are decompositions:

11 + 105653 = 105664
101 + 105563 = 105664
107 + 105557 = 105664
131 + 105533 = 105664
137 + 105527 = 105664
173 + 105491 = 105664
197 + 105467 = 105664
227 + 105437 = 105664

Showing the first eight; more decompositions exist.
