Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 966638, here are decompositions:

7 + 966631 = 966638
19 + 966619 = 966638
139 + 966499 = 966638
157 + 966481 = 966638
199 + 966439 = 966638
229 + 966409 = 966638
331 + 966307 = 966638
367 + 966271 = 966638

Showing the first eight; more decompositions exist.
