Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671808, here are decompositions:

97 + 8671711 = 8671808
139 + 8671669 = 8671808
307 + 8671501 = 8671808
337 + 8671471 = 8671808
367 + 8671441 = 8671808
487 + 8671321 = 8671808
577 + 8671231 = 8671808
631 + 8671177 = 8671808

Showing the first eight; more decompositions exist.
