Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671664, here are decompositions:

31 + 8671633 = 8671664
163 + 8671501 = 8671664
193 + 8671471 = 8671664
223 + 8671441 = 8671664
271 + 8671393 = 8671664
283 + 8671381 = 8671664
373 + 8671291 = 8671664
433 + 8671231 = 8671664

Showing the first eight; more decompositions exist.
