Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464968, here are decompositions:

181 + 31464787 = 31464968
211 + 31464757 = 31464968
349 + 31464619 = 31464968
397 + 31464571 = 31464968
421 + 31464547 = 31464968
487 + 31464481 = 31464968
541 + 31464427 = 31464968
547 + 31464421 = 31464968

Showing the first eight; more decompositions exist.
