Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105606, here are decompositions:

5 + 105601 = 105606
43 + 105563 = 105606
73 + 105533 = 105606
79 + 105527 = 105606
89 + 105517 = 105606
97 + 105509 = 105606
103 + 105503 = 105606
107 + 105499 = 105606

Showing the first eight; more decompositions exist.
