Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105444, here are decompositions:

7 + 105437 = 105444
37 + 105407 = 105444
43 + 105401 = 105444
47 + 105397 = 105444
71 + 105373 = 105444
83 + 105361 = 105444
103 + 105341 = 105444
107 + 105337 = 105444

Showing the first eight; more decompositions exist.
