Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105124, here are decompositions:

17 + 105107 = 105124
53 + 105071 = 105124
101 + 105023 = 105124
137 + 104987 = 105124
191 + 104933 = 105124
233 + 104891 = 105124
293 + 104831 = 105124
401 + 104723 = 105124

Showing the first eight; more decompositions exist.
