Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105456, here are decompositions:

7 + 105449 = 105456
19 + 105437 = 105456
59 + 105397 = 105456
67 + 105389 = 105456
83 + 105373 = 105456
89 + 105367 = 105456
97 + 105359 = 105456
137 + 105319 = 105456

Showing the first eight; more decompositions exist.
