Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667542, here are decompositions:

3 + 8667539 = 8667542
31 + 8667511 = 8667542
139 + 8667403 = 8667542
193 + 8667349 = 8667542
223 + 8667319 = 8667542
229 + 8667313 = 8667542
241 + 8667301 = 8667542
271 + 8667271 = 8667542

Showing the first eight; more decompositions exist.
