Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104180, here are decompositions:

7 + 104173 = 104180
19 + 104161 = 104180
31 + 104149 = 104180
61 + 104119 = 104180
67 + 104113 = 104180
73 + 104107 = 104180
127 + 104053 = 104180
199 + 103981 = 104180

Showing the first eight; more decompositions exist.
