Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637086, here are decompositions:

19 + 8637067 = 8637086
79 + 8637007 = 8637086
97 + 8636989 = 8637086
127 + 8636959 = 8637086
163 + 8636923 = 8637086
193 + 8636893 = 8637086
229 + 8636857 = 8637086
307 + 8636779 = 8637086

Showing the first eight; more decompositions exist.
