Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531212, here are decompositions:

43 + 531169 = 531212
79 + 531133 = 531212
109 + 531103 = 531212
223 + 530989 = 531212
229 + 530983 = 531212
379 + 530833 = 531212
439 + 530773 = 531212
499 + 530713 = 531212

Showing the first eight; more decompositions exist.
