Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607640, here are decompositions:

3 + 8607637 = 8607640
11 + 8607629 = 8607640
53 + 8607587 = 8607640
101 + 8607539 = 8607640
191 + 8607449 = 8607640
227 + 8607413 = 8607640
233 + 8607407 = 8607640
257 + 8607383 = 8607640

Showing the first eight; more decompositions exist.
