Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187564, here are decompositions:

5 + 187559 = 187564
17 + 187547 = 187564
101 + 187463 = 187564
131 + 187433 = 187564
191 + 187373 = 187564
197 + 187367 = 187564
227 + 187337 = 187564
347 + 187217 = 187564

Showing the first eight; more decompositions exist.
