Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680218, here are decompositions:

5 + 8680213 = 8680218
17 + 8680201 = 8680218
31 + 8680187 = 8680218
47 + 8680171 = 8680218
61 + 8680157 = 8680218
97 + 8680121 = 8680218
181 + 8680037 = 8680218
191 + 8680027 = 8680218

Showing the first eight; more decompositions exist.
