Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105210, here are decompositions:

11 + 105199 = 105210
37 + 105173 = 105210
43 + 105167 = 105210
67 + 105143 = 105210
73 + 105137 = 105210
103 + 105107 = 105210
113 + 105097 = 105210
139 + 105071 = 105210

Showing the first eight; more decompositions exist.
