Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981914, here are decompositions:

97 + 981817 = 981914
103 + 981811 = 981914
211 + 981703 = 981914
223 + 981691 = 981914
277 + 981637 = 981914
313 + 981601 = 981914
337 + 981577 = 981914
397 + 981517 = 981914

Showing the first eight; more decompositions exist.
