Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667842, here are decompositions:

13 + 8667829 = 8667842
109 + 8667733 = 8667842
181 + 8667661 = 8667842
229 + 8667613 = 8667842
241 + 8667601 = 8667842
283 + 8667559 = 8667842
331 + 8667511 = 8667842
439 + 8667403 = 8667842

Showing the first eight; more decompositions exist.
