Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187716, here are decompositions:

5 + 187711 = 187716
17 + 187699 = 187716
29 + 187687 = 187716
47 + 187669 = 187716
79 + 187637 = 187716
83 + 187633 = 187716
157 + 187559 = 187716
239 + 187477 = 187716

Showing the first eight; more decompositions exist.
