Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987676, here are decompositions:

17 + 987659 = 987676
83 + 987593 = 987676
89 + 987587 = 987676
167 + 987509 = 987676
293 + 987383 = 987676
383 + 987293 = 987676
449 + 987227 = 987676
467 + 987209 = 987676

Showing the first eight; more decompositions exist.
