Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477624, here are decompositions:

41 + 31477583 = 31477624
47 + 31477577 = 31477624
53 + 31477571 = 31477624
71 + 31477553 = 31477624
197 + 31477427 = 31477624
443 + 31477181 = 31477624
461 + 31477163 = 31477624
557 + 31477067 = 31477624

Showing the first eight; more decompositions exist.
