Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613238, here are decompositions:

17 + 8613221 = 8613238
89 + 8613149 = 8613238
131 + 8613107 = 8613238
149 + 8613089 = 8613238
191 + 8613047 = 8613238
197 + 8613041 = 8613238
269 + 8612969 = 8613238
281 + 8612957 = 8613238

Showing the first eight; more decompositions exist.
