Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105608, here are decompositions:

7 + 105601 = 105608
67 + 105541 = 105608
79 + 105529 = 105608
109 + 105499 = 105608
211 + 105397 = 105608
229 + 105379 = 105608
241 + 105367 = 105608
271 + 105337 = 105608

Showing the first eight; more decompositions exist.
