Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671800, here are decompositions:

31 + 8671769 = 8671800
61 + 8671739 = 8671800
79 + 8671721 = 8671800
89 + 8671711 = 8671800
103 + 8671697 = 8671800
131 + 8671669 = 8671800
167 + 8671633 = 8671800
211 + 8671589 = 8671800

Showing the first eight; more decompositions exist.
