Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999968, here are decompositions:

7 + 999961 = 999968
37 + 999931 = 999968
61 + 999907 = 999968
199 + 999769 = 999968
241 + 999727 = 999968
337 + 999631 = 999968
439 + 999529 = 999968
661 + 999307 = 999968

Showing the first eight; more decompositions exist.
