Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471712, here are decompositions:

31 + 31471681 = 31471712
73 + 31471639 = 31471712
79 + 31471633 = 31471712
163 + 31471549 = 31471712
499 + 31471213 = 31471712
541 + 31471171 = 31471712
619 + 31471093 = 31471712
661 + 31471051 = 31471712

Showing the first eight; more decompositions exist.
