Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667458, here are decompositions:

31 + 8667427 = 8667458
109 + 8667349 = 8667458
139 + 8667319 = 8667458
157 + 8667301 = 8667458
307 + 8667151 = 8667458
337 + 8667121 = 8667458
379 + 8667079 = 8667458
577 + 8666881 = 8667458

Showing the first eight; more decompositions exist.
