Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187682, here are decompositions:

13 + 187669 = 187682
31 + 187651 = 187682
43 + 187639 = 187682
109 + 187573 = 187682
151 + 187531 = 187682
211 + 187471 = 187682
241 + 187441 = 187682
379 + 187303 = 187682

Showing the first eight; more decompositions exist.
