Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531794, here are decompositions:

127 + 531667 = 531794
157 + 531637 = 531794
163 + 531631 = 531794
181 + 531613 = 531794
223 + 531571 = 531794
313 + 531481 = 531794
337 + 531457 = 531794
457 + 531337 = 531794

Showing the first eight; more decompositions exist.
