Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104220, here are decompositions:

13 + 104207 = 104220
37 + 104183 = 104220
41 + 104179 = 104220
47 + 104173 = 104220
59 + 104161 = 104220
71 + 104149 = 104220
73 + 104147 = 104220
97 + 104123 = 104220

Showing the first eight; more decompositions exist.
