Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664218, here are decompositions:

37 + 8664181 = 8664218
61 + 8664157 = 8664218
109 + 8664109 = 8664218
181 + 8664037 = 8664218
349 + 8663869 = 8664218
397 + 8663821 = 8664218
421 + 8663797 = 8664218
499 + 8663719 = 8664218

Showing the first eight; more decompositions exist.
