Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613646, here are decompositions:

23 + 8613623 = 8613646
29 + 8613617 = 8613646
317 + 8613329 = 8613646
347 + 8613299 = 8613646
557 + 8613089 = 8613646
599 + 8613047 = 8613646
677 + 8612969 = 8613646
719 + 8612927 = 8613646

Showing the first eight; more decompositions exist.
