Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105618, here are decompositions:

5 + 105613 = 105618
11 + 105607 = 105618
17 + 105601 = 105618
61 + 105557 = 105618
89 + 105529 = 105618
101 + 105517 = 105618
109 + 105509 = 105618
127 + 105491 = 105618

Showing the first eight; more decompositions exist.
