Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667218, here are decompositions:

67 + 8667151 = 8667218
97 + 8667121 = 8667218
139 + 8667079 = 8667218
229 + 8666989 = 8667218
337 + 8666881 = 8667218
379 + 8666839 = 8667218
409 + 8666809 = 8667218
421 + 8666797 = 8667218

Showing the first eight; more decompositions exist.
