Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531662, here are decompositions:

31 + 531631 = 531662
73 + 531589 = 531662
181 + 531481 = 531662
331 + 531331 = 531662
409 + 531253 = 531662
433 + 531229 = 531662
499 + 531163 = 531662
541 + 531121 = 531662

Showing the first eight; more decompositions exist.
