Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732986, here are decompositions:

23 + 8732963 = 8732986
29 + 8732957 = 8732986
107 + 8732879 = 8732986
167 + 8732819 = 8732986
179 + 8732807 = 8732986
347 + 8732639 = 8732986
359 + 8732627 = 8732986
557 + 8732429 = 8732986

Showing the first eight; more decompositions exist.
