Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105678, here are decompositions:

5 + 105673 = 105678
11 + 105667 = 105678
29 + 105649 = 105678
59 + 105619 = 105678
71 + 105607 = 105678
137 + 105541 = 105678
149 + 105529 = 105678
151 + 105527 = 105678

Showing the first eight; more decompositions exist.
