Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452968, here are decompositions:

67 + 31452901 = 31452968
109 + 31452859 = 31452968
139 + 31452829 = 31452968
199 + 31452769 = 31452968
229 + 31452739 = 31452968
241 + 31452727 = 31452968
397 + 31452571 = 31452968
439 + 31452529 = 31452968

Showing the first eight; more decompositions exist.
