Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187892, here are decompositions:

31 + 187861 = 187892
181 + 187711 = 187892
193 + 187699 = 187892
223 + 187669 = 187892
241 + 187651 = 187892
379 + 187513 = 187892
421 + 187471 = 187892
499 + 187393 = 187892

Showing the first eight; more decompositions exist.
