Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531774, here are decompositions:

43 + 531731 = 531774
73 + 531701 = 531774
101 + 531673 = 531774
107 + 531667 = 531774
137 + 531637 = 531774
151 + 531623 = 531774
163 + 531611 = 531774
193 + 531581 = 531774

Showing the first eight; more decompositions exist.
