Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681564, here are decompositions:

61 + 8681503 = 8681564
97 + 8681467 = 8681564
163 + 8681401 = 8681564
223 + 8681341 = 8681564
277 + 8681287 = 8681564
313 + 8681251 = 8681564
373 + 8681191 = 8681564
433 + 8681131 = 8681564

Showing the first eight; more decompositions exist.
