Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531968, here are decompositions:

67 + 531901 = 531968
97 + 531871 = 531968
127 + 531841 = 531968
331 + 531637 = 531968
337 + 531631 = 531968
379 + 531589 = 531968
397 + 531571 = 531968
421 + 531547 = 531968

Showing the first eight; more decompositions exist.
