Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671394, here are decompositions:

13 + 8671381 = 8671394
31 + 8671363 = 8671394
73 + 8671321 = 8671394
103 + 8671291 = 8671394
163 + 8671231 = 8671394
331 + 8671063 = 8671394
337 + 8671057 = 8671394
397 + 8670997 = 8671394

Showing the first eight; more decompositions exist.
