Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105150, here are decompositions:

7 + 105143 = 105150
13 + 105137 = 105150
43 + 105107 = 105150
53 + 105097 = 105150
79 + 105071 = 105150
113 + 105037 = 105150
127 + 105023 = 105150
131 + 105019 = 105150

Showing the first eight; more decompositions exist.
