Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464852, here are decompositions:

31 + 31464821 = 31464852
43 + 31464809 = 31464852
71 + 31464781 = 31464852
151 + 31464701 = 31464852
233 + 31464619 = 31464852
271 + 31464581 = 31464852
281 + 31464571 = 31464852
359 + 31464493 = 31464852

Showing the first eight; more decompositions exist.
