Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187492, here are decompositions:

23 + 187469 = 187492
29 + 187463 = 187492
59 + 187433 = 187492
83 + 187409 = 187492
113 + 187379 = 187492
131 + 187361 = 187492
269 + 187223 = 187492
281 + 187211 = 187492

Showing the first eight; more decompositions exist.
