Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104208, here are decompositions:

29 + 104179 = 104208
47 + 104161 = 104208
59 + 104149 = 104208
61 + 104147 = 104208
89 + 104119 = 104208
101 + 104107 = 104208
149 + 104059 = 104208
199 + 104009 = 104208

Showing the first eight; more decompositions exist.
