Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667284, here are decompositions:

13 + 8667271 = 8667284
163 + 8667121 = 8667284
181 + 8667103 = 8667284
331 + 8666953 = 8667284
421 + 8666863 = 8667284
487 + 8666797 = 8667284
601 + 8666683 = 8667284
751 + 8666533 = 8667284

Showing the first eight; more decompositions exist.
