Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667848, here are decompositions:

19 + 8667829 = 8667848
127 + 8667721 = 8667848
151 + 8667697 = 8667848
337 + 8667511 = 8667848
421 + 8667427 = 8667848
499 + 8667349 = 8667848
547 + 8667301 = 8667848
577 + 8667271 = 8667848

Showing the first eight; more decompositions exist.
