Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464824, here are decompositions:

3 + 31464821 = 31464824
37 + 31464787 = 31464824
43 + 31464781 = 31464824
67 + 31464757 = 31464824
277 + 31464547 = 31464824
331 + 31464493 = 31464824
373 + 31464451 = 31464824
397 + 31464427 = 31464824

Showing the first eight; more decompositions exist.
