Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105354, here are decompositions:

13 + 105341 = 105354
17 + 105337 = 105354
23 + 105331 = 105354
31 + 105323 = 105354
101 + 105253 = 105354
103 + 105251 = 105354
127 + 105227 = 105354
181 + 105173 = 105354

Showing the first eight; more decompositions exist.
