Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187768, here are decompositions:

5 + 187763 = 187768
17 + 187751 = 187768
47 + 187721 = 187768
107 + 187661 = 187768
131 + 187637 = 187768
137 + 187631 = 187768
359 + 187409 = 187768
389 + 187379 = 187768

Showing the first eight; more decompositions exist.
