Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187552, here are decompositions:

5 + 187547 = 187552
83 + 187469 = 187552
89 + 187463 = 187552
173 + 187379 = 187552
179 + 187373 = 187552
191 + 187361 = 187552
359 + 187193 = 187552
389 + 187163 = 187552

Showing the first eight; more decompositions exist.
