Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187582, here are decompositions:

23 + 187559 = 187582
113 + 187469 = 187582
149 + 187433 = 187582
173 + 187409 = 187582
233 + 187349 = 187582
359 + 187223 = 187582
389 + 187193 = 187582
401 + 187181 = 187582

Showing the first eight; more decompositions exist.
