Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671242, here are decompositions:

11 + 8671231 = 8671242
23 + 8671219 = 8671242
109 + 8671133 = 8671242
179 + 8671063 = 8671242
191 + 8671051 = 8671242
211 + 8671031 = 8671242
233 + 8671009 = 8671242
373 + 8670869 = 8671242

Showing the first eight; more decompositions exist.
