Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105612, here are decompositions:

5 + 105607 = 105612
11 + 105601 = 105612
71 + 105541 = 105612
79 + 105533 = 105612
83 + 105529 = 105612
103 + 105509 = 105612
109 + 105503 = 105612
113 + 105499 = 105612

Showing the first eight; more decompositions exist.
