Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607578, here are decompositions:

97 + 8607481 = 8607578
151 + 8607427 = 8607578
181 + 8607397 = 8607578
271 + 8607307 = 8607578
307 + 8607271 = 8607578
337 + 8607241 = 8607578
439 + 8607139 = 8607578
619 + 8606959 = 8607578

Showing the first eight; more decompositions exist.
