Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607420, here are decompositions:

7 + 8607413 = 8607420
11 + 8607409 = 8607420
13 + 8607407 = 8607420
23 + 8607397 = 8607420
37 + 8607383 = 8607420
43 + 8607377 = 8607420
47 + 8607373 = 8607420
79 + 8607341 = 8607420

Showing the first eight; more decompositions exist.
