Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981340, here are decompositions:

29 + 981311 = 981340
53 + 981287 = 981340
131 + 981209 = 981340
167 + 981173 = 981340
263 + 981077 = 981340
317 + 981023 = 981340
383 + 980957 = 981340
419 + 980921 = 981340

Showing the first eight; more decompositions exist.
