Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607618, here are decompositions:

17 + 8607601 = 8607618
31 + 8607587 = 8607618
79 + 8607539 = 8607618
137 + 8607481 = 8607618
139 + 8607479 = 8607618
191 + 8607427 = 8607618
211 + 8607407 = 8607618
241 + 8607377 = 8607618

Showing the first eight; more decompositions exist.
