Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105328, here are decompositions:

5 + 105323 = 105328
59 + 105269 = 105328
89 + 105239 = 105328
101 + 105227 = 105328
191 + 105137 = 105328
257 + 105071 = 105328
449 + 104879 = 105328
479 + 104849 = 105328

Showing the first eight; more decompositions exist.
