Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671544, here are decompositions:

43 + 8671501 = 8671544
73 + 8671471 = 8671544
97 + 8671447 = 8671544
103 + 8671441 = 8671544
151 + 8671393 = 8671544
163 + 8671381 = 8671544
181 + 8671363 = 8671544
223 + 8671321 = 8671544

Showing the first eight; more decompositions exist.
