Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105430, here are decompositions:

23 + 105407 = 105430
29 + 105401 = 105430
41 + 105389 = 105430
71 + 105359 = 105430
89 + 105341 = 105430
107 + 105323 = 105430
167 + 105263 = 105430
179 + 105251 = 105430

Showing the first eight; more decompositions exist.
