Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105372, here are decompositions:

5 + 105367 = 105372
11 + 105361 = 105372
13 + 105359 = 105372
31 + 105341 = 105372
41 + 105331 = 105372
53 + 105319 = 105372
103 + 105269 = 105372
109 + 105263 = 105372

Showing the first eight; more decompositions exist.
