Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981474, here are decompositions:

7 + 981467 = 981474
23 + 981451 = 981474
31 + 981443 = 981474
37 + 981437 = 981474
83 + 981391 = 981474
97 + 981377 = 981474
101 + 981373 = 981474
163 + 981311 = 981474

Showing the first eight; more decompositions exist.
