Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566968, here are decompositions:

67 + 31566901 = 31566968
151 + 31566817 = 31566968
337 + 31566631 = 31566968
379 + 31566589 = 31566968
409 + 31566559 = 31566968
421 + 31566547 = 31566968
487 + 31566481 = 31566968
541 + 31566427 = 31566968

Showing the first eight; more decompositions exist.
