Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671238, here are decompositions:

7 + 8671231 = 8671238
19 + 8671219 = 8671238
61 + 8671177 = 8671238
139 + 8671099 = 8671238
181 + 8671057 = 8671238
229 + 8671009 = 8671238
241 + 8670997 = 8671238
487 + 8670751 = 8671238

Showing the first eight; more decompositions exist.
