Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105806, here are decompositions:

37 + 105769 = 105806
73 + 105733 = 105806
79 + 105727 = 105806
139 + 105667 = 105806
157 + 105649 = 105806
193 + 105613 = 105806
199 + 105607 = 105806
277 + 105529 = 105806

Showing the first eight; more decompositions exist.
