Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654660, here are decompositions:

19 + 8654641 = 8654660
43 + 8654617 = 8654660
97 + 8654563 = 8654660
139 + 8654521 = 8654660
193 + 8654467 = 8654660
199 + 8654461 = 8654660
229 + 8654431 = 8654660
271 + 8654389 = 8654660

Showing the first eight; more decompositions exist.
