Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746218, here are decompositions:

11 + 8746207 = 8746218
101 + 8746117 = 8746218
149 + 8746069 = 8746218
181 + 8746037 = 8746218
227 + 8745991 = 8746218
337 + 8745881 = 8746218
389 + 8745829 = 8746218
401 + 8745817 = 8746218

Showing the first eight; more decompositions exist.
