Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105630, here are decompositions:

11 + 105619 = 105630
17 + 105613 = 105630
23 + 105607 = 105630
29 + 105601 = 105630
67 + 105563 = 105630
73 + 105557 = 105630
89 + 105541 = 105630
97 + 105533 = 105630

Showing the first eight; more decompositions exist.
