Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187454, here are decompositions:

13 + 187441 = 187454
31 + 187423 = 187454
37 + 187417 = 187454
61 + 187393 = 187454
67 + 187387 = 187454
151 + 187303 = 187454
181 + 187273 = 187454
277 + 187177 = 187454

Showing the first eight; more decompositions exist.
