Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 983666, here are decompositions:

7 + 983659 = 983666
109 + 983557 = 983666
139 + 983527 = 983666
223 + 983443 = 983666
337 + 983329 = 983666
349 + 983317 = 983666
367 + 983299 = 983666
433 + 983233 = 983666

Showing the first eight; more decompositions exist.
