Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105088, here are decompositions:

17 + 105071 = 105088
89 + 104999 = 105088
101 + 104987 = 105088
197 + 104891 = 105088
239 + 104849 = 105088
257 + 104831 = 105088
359 + 104729 = 105088
449 + 104639 = 105088

Showing the first eight; more decompositions exist.
