Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105118, here are decompositions:

11 + 105107 = 105118
47 + 105071 = 105118
131 + 104987 = 105118
227 + 104891 = 105118
239 + 104879 = 105118
269 + 104849 = 105118
317 + 104801 = 105118
359 + 104759 = 105118

Showing the first eight; more decompositions exist.
