Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187916, here are decompositions:

7 + 187909 = 187916
19 + 187897 = 187916
73 + 187843 = 187916
229 + 187687 = 187916
277 + 187639 = 187916
283 + 187633 = 187916
409 + 187507 = 187916
439 + 187477 = 187916

Showing the first eight; more decompositions exist.
