Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531456, here are decompositions:

73 + 531383 = 531456
97 + 531359 = 531456
103 + 531353 = 531456
109 + 531347 = 531456
113 + 531343 = 531456
157 + 531299 = 531456
193 + 531263 = 531456
227 + 531229 = 531456

Showing the first eight; more decompositions exist.
