Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681804, here are decompositions:

67 + 8681737 = 8681804
73 + 8681731 = 8681804
97 + 8681707 = 8681804
181 + 8681623 = 8681804
331 + 8681473 = 8681804
337 + 8681467 = 8681804
463 + 8681341 = 8681804
487 + 8681317 = 8681804

Showing the first eight; more decompositions exist.
