Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105386, here are decompositions:

7 + 105379 = 105386
13 + 105373 = 105386
19 + 105367 = 105386
67 + 105319 = 105386
109 + 105277 = 105386
157 + 105229 = 105386
349 + 105037 = 105386
367 + 105019 = 105386

Showing the first eight; more decompositions exist.
