Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671718, here are decompositions:

7 + 8671711 = 8671718
79 + 8671639 = 8671718
199 + 8671519 = 8671718
271 + 8671447 = 8671718
277 + 8671441 = 8671718
337 + 8671381 = 8671718
379 + 8671339 = 8671718
397 + 8671321 = 8671718

Showing the first eight; more decompositions exist.
