Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104172, here are decompositions:

11 + 104161 = 104172
23 + 104149 = 104172
53 + 104119 = 104172
59 + 104113 = 104172
83 + 104089 = 104172
113 + 104059 = 104172
139 + 104033 = 104172
151 + 104021 = 104172

Showing the first eight; more decompositions exist.
