Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186564, here are decompositions:

13 + 186551 = 186564
83 + 186481 = 186564
113 + 186451 = 186564
127 + 186437 = 186564
167 + 186397 = 186564
173 + 186391 = 186564
263 + 186301 = 186564
281 + 186283 = 186564

Showing the first eight; more decompositions exist.
