Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671574, here are decompositions:

73 + 8671501 = 8671574
103 + 8671471 = 8671574
127 + 8671447 = 8671574
181 + 8671393 = 8671574
193 + 8671381 = 8671574
211 + 8671363 = 8671574
283 + 8671291 = 8671574
397 + 8671177 = 8671574

Showing the first eight; more decompositions exist.
