Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105412, here are decompositions:

5 + 105407 = 105412
11 + 105401 = 105412
23 + 105389 = 105412
53 + 105359 = 105412
71 + 105341 = 105412
89 + 105323 = 105412
149 + 105263 = 105412
173 + 105239 = 105412

Showing the first eight; more decompositions exist.
