Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105008, here are decompositions:

37 + 104971 = 105008
61 + 104947 = 105008
97 + 104911 = 105008
139 + 104869 = 105008
157 + 104851 = 105008
181 + 104827 = 105008
229 + 104779 = 105008
307 + 104701 = 105008

Showing the first eight; more decompositions exist.
