Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671408, here are decompositions:

41 + 8671367 = 8671408
47 + 8671361 = 8671408
101 + 8671307 = 8671408
257 + 8671151 = 8671408
281 + 8671127 = 8671408
311 + 8671097 = 8671408
401 + 8671007 = 8671408
419 + 8670989 = 8671408

Showing the first eight; more decompositions exist.
