Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477584, here are decompositions:

7 + 31477577 = 31477584
13 + 31477571 = 31477584
23 + 31477561 = 31477584
31 + 31477553 = 31477584
41 + 31477543 = 31477584
71 + 31477513 = 31477584
101 + 31477483 = 31477584
137 + 31477447 = 31477584

Showing the first eight; more decompositions exist.
