Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987832, here are decompositions:

11 + 987821 = 987832
23 + 987809 = 987832
29 + 987803 = 987832
173 + 987659 = 987832
233 + 987599 = 987832
239 + 987593 = 987832
359 + 987473 = 987832
449 + 987383 = 987832

Showing the first eight; more decompositions exist.
