Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105370, here are decompositions:

3 + 105367 = 105370
11 + 105359 = 105370
29 + 105341 = 105370
47 + 105323 = 105370
101 + 105269 = 105370
107 + 105263 = 105370
131 + 105239 = 105370
197 + 105173 = 105370

Showing the first eight; more decompositions exist.
