Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531524, here are decompositions:

3 + 531521 = 531524
43 + 531481 = 531524
67 + 531457 = 531524
181 + 531343 = 531524
193 + 531331 = 531524
271 + 531253 = 531524
421 + 531103 = 531524
541 + 530983 = 531524

Showing the first eight; more decompositions exist.
