Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187636, here are decompositions:

3 + 187633 = 187636
5 + 187631 = 187636
89 + 187547 = 187636
167 + 187469 = 187636
173 + 187463 = 187636
227 + 187409 = 187636
257 + 187379 = 187636
263 + 187373 = 187636

Showing the first eight; more decompositions exist.
