Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671406, here are decompositions:

13 + 8671393 = 8671406
43 + 8671363 = 8671406
67 + 8671339 = 8671406
157 + 8671249 = 8671406
229 + 8671177 = 8671406
307 + 8671099 = 8671406
349 + 8671057 = 8671406
397 + 8671009 = 8671406

Showing the first eight; more decompositions exist.
