Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671888, here are decompositions:

149 + 8671739 = 8671888
167 + 8671721 = 8671888
179 + 8671709 = 8671888
191 + 8671697 = 8671888
257 + 8671631 = 8671888
389 + 8671499 = 8671888
419 + 8671469 = 8671888
431 + 8671457 = 8671888

Showing the first eight; more decompositions exist.
