Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671880, here are decompositions:

43 + 8671837 = 8671880
211 + 8671669 = 8671880
241 + 8671639 = 8671880
307 + 8671573 = 8671880
331 + 8671549 = 8671880
379 + 8671501 = 8671880
409 + 8671471 = 8671880
433 + 8671447 = 8671880

Showing the first eight; more decompositions exist.
