Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999868, here are decompositions:

5 + 999863 = 999868
59 + 999809 = 999868
197 + 999671 = 999868
257 + 999611 = 999868
269 + 999599 = 999868
347 + 999521 = 999868
431 + 999437 = 999868
479 + 999389 = 999868

Showing the first eight; more decompositions exist.
