Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531792, here are decompositions:

61 + 531731 = 531792
103 + 531689 = 531792
179 + 531613 = 531792
181 + 531611 = 531792
211 + 531581 = 531792
223 + 531569 = 531792
241 + 531551 = 531792
271 + 531521 = 531792

Showing the first eight; more decompositions exist.
