Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104212, here are decompositions:

5 + 104207 = 104212
29 + 104183 = 104212
89 + 104123 = 104212
179 + 104033 = 104212
191 + 104021 = 104212
233 + 103979 = 104212
293 + 103919 = 104212
401 + 103811 = 104212

Showing the first eight; more decompositions exist.
