Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187498, here are decompositions:

29 + 187469 = 187498
89 + 187409 = 187498
131 + 187367 = 187498
137 + 187361 = 187498
149 + 187349 = 187498
281 + 187217 = 187498
317 + 187181 = 187498
359 + 187139 = 187498

Showing the first eight; more decompositions exist.
