Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607664, here are decompositions:

5 + 8607659 = 8607664
11 + 8607653 = 8607664
101 + 8607563 = 8607664
251 + 8607413 = 8607664
257 + 8607407 = 8607664
281 + 8607383 = 8607664
293 + 8607371 = 8607664
383 + 8607281 = 8607664

Showing the first eight; more decompositions exist.
