Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105616, here are decompositions:

3 + 105613 = 105616
53 + 105563 = 105616
59 + 105557 = 105616
83 + 105533 = 105616
89 + 105527 = 105616
107 + 105509 = 105616
113 + 105503 = 105616
149 + 105467 = 105616

Showing the first eight; more decompositions exist.
