Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667344, here are decompositions:

31 + 8667313 = 8667344
43 + 8667301 = 8667344
73 + 8667271 = 8667344
193 + 8667151 = 8667344
223 + 8667121 = 8667344
241 + 8667103 = 8667344
463 + 8666881 = 8667344
547 + 8666797 = 8667344

Showing the first eight; more decompositions exist.
