Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531444, here are decompositions:

61 + 531383 = 531444
97 + 531347 = 531444
101 + 531343 = 531444
107 + 531337 = 531444
113 + 531331 = 531444
157 + 531287 = 531444
163 + 531281 = 531444
181 + 531263 = 531444

Showing the first eight; more decompositions exist.
