Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609218, here are decompositions:

11 + 8609207 = 8609218
89 + 8609129 = 8609218
131 + 8609087 = 8609218
311 + 8608907 = 8609218
347 + 8608871 = 8609218
389 + 8608829 = 8609218
419 + 8608799 = 8609218
467 + 8608751 = 8609218

Showing the first eight; more decompositions exist.
