Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981454, here are decompositions:

3 + 981451 = 981454
11 + 981443 = 981454
17 + 981437 = 981454
167 + 981287 = 981454
191 + 981263 = 981454
233 + 981221 = 981454
281 + 981173 = 981454
317 + 981137 = 981454

Showing the first eight; more decompositions exist.
