Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667844, here are decompositions:

23 + 8667821 = 8667844
47 + 8667797 = 8667844
137 + 8667707 = 8667844
167 + 8667677 = 8667844
191 + 8667653 = 8667844
233 + 8667611 = 8667844
281 + 8667563 = 8667844
347 + 8667497 = 8667844

Showing the first eight; more decompositions exist.
