Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981410, here are decompositions:

13 + 981397 = 981410
19 + 981391 = 981410
37 + 981373 = 981410
109 + 981301 = 981410
127 + 981283 = 981410
139 + 981271 = 981410
211 + 981199 = 981410
223 + 981187 = 981410

Showing the first eight; more decompositions exist.
