Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671418, here are decompositions:

37 + 8671381 = 8671418
79 + 8671339 = 8671418
97 + 8671321 = 8671418
127 + 8671291 = 8671418
199 + 8671219 = 8671418
241 + 8671177 = 8671418
271 + 8671147 = 8671418
367 + 8671051 = 8671418

Showing the first eight; more decompositions exist.
