Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105126, here are decompositions:

19 + 105107 = 105126
29 + 105097 = 105126
89 + 105037 = 105126
103 + 105023 = 105126
107 + 105019 = 105126
127 + 104999 = 105126
139 + 104987 = 105126
167 + 104959 = 105126

Showing the first eight; more decompositions exist.
