Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649986, here are decompositions:

13 + 8649973 = 8649986
19 + 8649967 = 8649986
139 + 8649847 = 8649986
193 + 8649793 = 8649986
223 + 8649763 = 8649986
229 + 8649757 = 8649986
283 + 8649703 = 8649986
349 + 8649637 = 8649986

Showing the first eight; more decompositions exist.
