Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981354, here are decompositions:

43 + 981311 = 981354
53 + 981301 = 981354
67 + 981287 = 981354
71 + 981283 = 981354
83 + 981271 = 981354
113 + 981241 = 981354
167 + 981187 = 981354
181 + 981173 = 981354

Showing the first eight; more decompositions exist.
