Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670238, here are decompositions:

41 + 8670197 = 8670238
47 + 8670191 = 8670238
131 + 8670107 = 8670238
149 + 8670089 = 8670238
167 + 8670071 = 8670238
197 + 8670041 = 8670238
257 + 8669981 = 8670238
359 + 8669879 = 8670238

Showing the first eight; more decompositions exist.
