Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001678, here are decompositions:

19 + 1001659 = 1001678
109 + 1001569 = 1001678
127 + 1001551 = 1001678
151 + 1001527 = 1001678
211 + 1001467 = 1001678
277 + 1001401 = 1001678
331 + 1001347 = 1001678
367 + 1001311 = 1001678

Showing the first eight; more decompositions exist.
