Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187894, here are decompositions:

11 + 187883 = 187894
17 + 187877 = 187894
23 + 187871 = 187894
71 + 187823 = 187894
101 + 187793 = 187894
107 + 187787 = 187894
131 + 187763 = 187894
173 + 187721 = 187894

Showing the first eight; more decompositions exist.
