Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105424, here are decompositions:

17 + 105407 = 105424
23 + 105401 = 105424
83 + 105341 = 105424
101 + 105323 = 105424
173 + 105251 = 105424
197 + 105227 = 105424
251 + 105173 = 105424
257 + 105167 = 105424

Showing the first eight; more decompositions exist.
