Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453064, here are decompositions:

43 + 31453021 = 31453064
163 + 31452901 = 31453064
271 + 31452793 = 31453064
337 + 31452727 = 31453064
397 + 31452667 = 31453064
457 + 31452607 = 31453064
547 + 31452517 = 31453064
571 + 31452493 = 31453064

Showing the first eight; more decompositions exist.
