Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672000, here are decompositions:

13 + 8671987 = 8672000
19 + 8671981 = 8672000
163 + 8671837 = 8672000
331 + 8671669 = 8672000
367 + 8671633 = 8672000
499 + 8671501 = 8672000
607 + 8671393 = 8672000
619 + 8671381 = 8672000

Showing the first eight; more decompositions exist.
