Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105628, here are decompositions:

71 + 105557 = 105628
101 + 105527 = 105628
137 + 105491 = 105628
179 + 105449 = 105628
191 + 105437 = 105628
227 + 105401 = 105628
239 + 105389 = 105628
269 + 105359 = 105628

Showing the first eight; more decompositions exist.
