Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981368, here are decompositions:

67 + 981301 = 981368
79 + 981289 = 981368
97 + 981271 = 981368
127 + 981241 = 981368
181 + 981187 = 981368
229 + 981139 = 981368
277 + 981091 = 981368
307 + 981061 = 981368

Showing the first eight; more decompositions exist.
