Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105018, here are decompositions:

19 + 104999 = 105018
31 + 104987 = 105018
47 + 104971 = 105018
59 + 104959 = 105018
71 + 104947 = 105018
101 + 104917 = 105018
107 + 104911 = 105018
127 + 104891 = 105018

Showing the first eight; more decompositions exist.
