Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105516, here are decompositions:

7 + 105509 = 105516
13 + 105503 = 105516
17 + 105499 = 105516
67 + 105449 = 105516
79 + 105437 = 105516
109 + 105407 = 105516
127 + 105389 = 105516
137 + 105379 = 105516

Showing the first eight; more decompositions exist.
