Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105822, here are decompositions:

5 + 105817 = 105822
53 + 105769 = 105822
61 + 105761 = 105822
71 + 105751 = 105822
89 + 105733 = 105822
131 + 105691 = 105822
139 + 105683 = 105822
149 + 105673 = 105822

Showing the first eight; more decompositions exist.
