Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104238, here are decompositions:

5 + 104233 = 104238
7 + 104231 = 104238
31 + 104207 = 104238
59 + 104179 = 104238
89 + 104149 = 104238
131 + 104107 = 104238
149 + 104089 = 104238
151 + 104087 = 104238

Showing the first eight; more decompositions exist.
