Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709458, here are decompositions:

97 + 8709361 = 8709458
157 + 8709301 = 8709458
229 + 8709229 = 8709458
271 + 8709187 = 8709458
337 + 8709121 = 8709458
379 + 8709079 = 8709458
487 + 8708971 = 8709458
547 + 8708911 = 8709458

Showing the first eight; more decompositions exist.
