Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609906, here are decompositions:

7 + 8609899 = 8609906
73 + 8609833 = 8609906
223 + 8609683 = 8609906
229 + 8609677 = 8609906
337 + 8609569 = 8609906
373 + 8609533 = 8609906
433 + 8609473 = 8609906
457 + 8609449 = 8609906

Showing the first eight; more decompositions exist.
