Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987826, here are decompositions:

5 + 987821 = 987826
17 + 987809 = 987826
23 + 987803 = 987826
29 + 987797 = 987826
113 + 987713 = 987826
167 + 987659 = 987826
227 + 987599 = 987826
233 + 987593 = 987826

Showing the first eight; more decompositions exist.
