Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187822, here are decompositions:

29 + 187793 = 187822
59 + 187763 = 187822
71 + 187751 = 187822
101 + 187721 = 187822
191 + 187631 = 187822
263 + 187559 = 187822
353 + 187469 = 187822
359 + 187463 = 187822

Showing the first eight; more decompositions exist.
