Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669258, here are decompositions:

7 + 8669251 = 8669258
19 + 8669239 = 8669258
79 + 8669179 = 8669258
151 + 8669107 = 8669258
307 + 8668951 = 8669258
421 + 8668837 = 8669258
457 + 8668801 = 8669258
547 + 8668711 = 8669258

Showing the first eight; more decompositions exist.
