Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105830, here are decompositions:

13 + 105817 = 105830
61 + 105769 = 105830
79 + 105751 = 105830
97 + 105733 = 105830
103 + 105727 = 105830
139 + 105691 = 105830
157 + 105673 = 105830
163 + 105667 = 105830

Showing the first eight; more decompositions exist.
