Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607646, here are decompositions:

17 + 8607629 = 8607646
59 + 8607587 = 8607646
83 + 8607563 = 8607646
107 + 8607539 = 8607646
167 + 8607479 = 8607646
197 + 8607449 = 8607646
233 + 8607413 = 8607646
239 + 8607407 = 8607646

Showing the first eight; more decompositions exist.
