Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531602, here are decompositions:

13 + 531589 = 531602
31 + 531571 = 531602
271 + 531331 = 531602
349 + 531253 = 531602
373 + 531229 = 531602
433 + 531169 = 531602
439 + 531163 = 531602
499 + 531103 = 531602

Showing the first eight; more decompositions exist.
