Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105080, here are decompositions:

43 + 105037 = 105080
61 + 105019 = 105080
109 + 104971 = 105080
127 + 104953 = 105080
163 + 104917 = 105080
211 + 104869 = 105080
229 + 104851 = 105080
277 + 104803 = 105080

Showing the first eight; more decompositions exist.
