Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187484, here are decompositions:

7 + 187477 = 187484
13 + 187471 = 187484
43 + 187441 = 187484
61 + 187423 = 187484
67 + 187417 = 187484
97 + 187387 = 187484
181 + 187303 = 187484
211 + 187273 = 187484

Showing the first eight; more decompositions exist.
