Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670218, here are decompositions:

61 + 8670157 = 8670218
181 + 8670037 = 8670218
211 + 8670007 = 8670218
229 + 8669989 = 8670218
307 + 8669911 = 8670218
397 + 8669821 = 8670218
547 + 8669671 = 8670218
607 + 8669611 = 8670218

Showing the first eight; more decompositions exist.
