Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592968, here are decompositions:

47 + 31592921 = 31592968
317 + 31592651 = 31592968
347 + 31592621 = 31592968
401 + 31592567 = 31592968
479 + 31592489 = 31592968
521 + 31592447 = 31592968
557 + 31592411 = 31592968
599 + 31592369 = 31592968

Showing the first eight; more decompositions exist.
