Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105486, here are decompositions:

19 + 105467 = 105486
37 + 105449 = 105486
79 + 105407 = 105486
89 + 105397 = 105486
97 + 105389 = 105486
107 + 105379 = 105486
113 + 105373 = 105486
127 + 105359 = 105486

Showing the first eight; more decompositions exist.
