Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981404, here are decompositions:

7 + 981397 = 981404
13 + 981391 = 981404
31 + 981373 = 981404
103 + 981301 = 981404
163 + 981241 = 981404
271 + 981133 = 981404
313 + 981091 = 981404
331 + 981073 = 981404

Showing the first eight; more decompositions exist.
