Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187494, here are decompositions:

17 + 187477 = 187494
23 + 187471 = 187494
31 + 187463 = 187494
53 + 187441 = 187494
61 + 187433 = 187494
71 + 187423 = 187494
101 + 187393 = 187494
107 + 187387 = 187494

Showing the first eight; more decompositions exist.
