Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187508, here are decompositions:

31 + 187477 = 187508
37 + 187471 = 187508
67 + 187441 = 187508
271 + 187237 = 187508
331 + 187177 = 187508
337 + 187171 = 187508
367 + 187141 = 187508
379 + 187129 = 187508

Showing the first eight; more decompositions exist.
