Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681774, here are decompositions:

37 + 8681737 = 8681774
43 + 8681731 = 8681774
67 + 8681707 = 8681774
151 + 8681623 = 8681774
271 + 8681503 = 8681774
307 + 8681467 = 8681774
373 + 8681401 = 8681774
397 + 8681377 = 8681774

Showing the first eight; more decompositions exist.
