Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671748, here are decompositions:

37 + 8671711 = 8671748
79 + 8671669 = 8671748
109 + 8671639 = 8671748
199 + 8671549 = 8671748
229 + 8671519 = 8671748
277 + 8671471 = 8671748
307 + 8671441 = 8671748
367 + 8671381 = 8671748

Showing the first eight; more decompositions exist.
