Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981494, here are decompositions:

13 + 981481 = 981494
43 + 981451 = 981494
97 + 981397 = 981494
103 + 981391 = 981494
193 + 981301 = 981494
211 + 981283 = 981494
223 + 981271 = 981494
307 + 981187 = 981494

Showing the first eight; more decompositions exist.
