Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166532, here are decompositions:

61 + 166471 = 166532
103 + 166429 = 166532
139 + 166393 = 166532
181 + 166351 = 166532
229 + 166303 = 166532
313 + 166219 = 166532
349 + 166183 = 166532
433 + 166099 = 166532

Showing the first eight; more decompositions exist.
