Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681540, here are decompositions:

37 + 8681503 = 8681540
67 + 8681473 = 8681540
73 + 8681467 = 8681540
139 + 8681401 = 8681540
163 + 8681377 = 8681540
181 + 8681359 = 8681540
199 + 8681341 = 8681540
223 + 8681317 = 8681540

Showing the first eight; more decompositions exist.
