Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607378, here are decompositions:

5 + 8607373 = 8607378
7 + 8607371 = 8607378
37 + 8607341 = 8607378
71 + 8607307 = 8607378
97 + 8607281 = 8607378
107 + 8607271 = 8607378
137 + 8607241 = 8607378
151 + 8607227 = 8607378

Showing the first eight; more decompositions exist.
