Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187556, here are decompositions:

43 + 187513 = 187556
79 + 187477 = 187556
139 + 187417 = 187556
163 + 187393 = 187556
283 + 187273 = 187556
337 + 187219 = 187556
367 + 187189 = 187556
379 + 187177 = 187556

Showing the first eight; more decompositions exist.
