Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607478, here are decompositions:

29 + 8607449 = 8607478
71 + 8607407 = 8607478
101 + 8607377 = 8607478
107 + 8607371 = 8607478
137 + 8607341 = 8607478
149 + 8607329 = 8607478
197 + 8607281 = 8607478
251 + 8607227 = 8607478

Showing the first eight; more decompositions exist.
