Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187940, here are decompositions:

13 + 187927 = 187940
19 + 187921 = 187940
31 + 187909 = 187940
43 + 187897 = 187940
79 + 187861 = 187940
97 + 187843 = 187940
229 + 187711 = 187940
241 + 187699 = 187940

Showing the first eight; more decompositions exist.
