Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105558, here are decompositions:

17 + 105541 = 105558
29 + 105529 = 105558
31 + 105527 = 105558
41 + 105517 = 105558
59 + 105499 = 105558
67 + 105491 = 105558
109 + 105449 = 105558
151 + 105407 = 105558

Showing the first eight; more decompositions exist.
