Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001668, here are decompositions:

29 + 1001639 = 1001668
47 + 1001621 = 1001668
137 + 1001531 = 1001668
167 + 1001501 = 1001668
257 + 1001411 = 1001668
281 + 1001387 = 1001668
347 + 1001321 = 1001668
389 + 1001279 = 1001668

Showing the first eight; more decompositions exist.
