Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981374, here are decompositions:

73 + 981301 = 981374
103 + 981271 = 981374
223 + 981151 = 981374
241 + 981133 = 981374
283 + 981091 = 981374
307 + 981067 = 981374
313 + 981061 = 981374
337 + 981037 = 981374

Showing the first eight; more decompositions exist.
