Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671436, here are decompositions:

43 + 8671393 = 8671436
73 + 8671363 = 8671436
97 + 8671339 = 8671436
337 + 8671099 = 8671436
373 + 8671063 = 8671436
379 + 8671057 = 8671436
439 + 8670997 = 8671436
727 + 8670709 = 8671436

Showing the first eight; more decompositions exist.
