Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607638, here are decompositions:

7 + 8607631 = 8607638
37 + 8607601 = 8607638
157 + 8607481 = 8607638
211 + 8607427 = 8607638
229 + 8607409 = 8607638
241 + 8607397 = 8607638
331 + 8607307 = 8607638
367 + 8607271 = 8607638

Showing the first eight; more decompositions exist.
