Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105878, here are decompositions:

7 + 105871 = 105878
61 + 105817 = 105878
109 + 105769 = 105878
127 + 105751 = 105878
151 + 105727 = 105878
211 + 105667 = 105878
229 + 105649 = 105878
271 + 105607 = 105878

Showing the first eight; more decompositions exist.
