Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105378, here are decompositions:

5 + 105373 = 105378
11 + 105367 = 105378
17 + 105361 = 105378
19 + 105359 = 105378
37 + 105341 = 105378
41 + 105337 = 105378
47 + 105331 = 105378
59 + 105319 = 105378

Showing the first eight; more decompositions exist.
